Walkthrough

Walkthrough is in progess of being uploaded. If you don't want to wait, you can buy the official, prettier version of it in PDF format **as** **DLC**.
For suggestions and questions, please let us know on the official Drain Mansion server.

## #1 - Starting Area

When you first start the game, you will be welcomed with a short cutscene introducing the premise of the game. You can skip this by pressing “Enter” (but it’s very short, so I don’t recommend skipping unless you really do not care about the story of the game).

You have the option to play the tutorial or skip it. I advise you not to skip it; it’s super short and is mainly for teaching you how to do the basic movements and interactions. Once you’re able to control the MC, you just need to go all the way to the right, reading the instructions on the signposts and doing as it tells you to. At the end, you have to open the locked door (marked with a red question mark) with the key you picked up right before and then leave the room.

The main gameplay of the game consists of you trying not to get caught by succubi, or if you do get caught, to escape. If you get caught, you can struggle by pressing the Enter and Space repeatedly, or the left-right arrow buttons.

**Note**: There’s also a door on your left where you can enable the Hardmode of the game. This guide will focus mainly on the normal mode, however I will leave notes in each section for some Hardmode specificities. Hardmode generally just means more traps and obstacles, faster or harder to escape enemies.

**Note**: Some areas and content, which this guide will also include, are only accessible if you stay a virgin throughout the entire playthrough. If you get caught, make sure to reload your last save if you want to access the bonus content. If the scene includes vaginal or anal sex, it will pop your cherry, so make sure you watch out for that. (It means that other means of intercourse doesn’t affect your V.)

Let’s get right into it!

Once you leave the room, you’ll arrive in a safe room. Save your game at the save spot, and interact with the bookshelf for some juicy Drain Mansion lore. You can cycle through the pages with the arrow buttons. There’s also a hiding spot in the far right if you want to try that out.
Once you leave the safe room, there will be a short cutscene of the first enemy (**Purple Succubus**). As you will see, this enemy has a skull above her head, which means that if she catches you, it’s game over. If you do not want to get caught, make sure to start running to the right immediately after the cutscene ends. There will be 3 crates you will have to jump through. Don’t get cocky upon seeing these crates because the succubus can and will jump over them as well - and she’s faster than you are.

To get the first 2 achievements, **Drained** and **Irresistible**, go back into the previous room and let the succubus catch you. Then reload the save and do the sequence again.
The next room has a new enemy type, the **Slime**. This one has no sight indicator and will not chase you even if you get close, so they’re easy to avoid. She will kill you if you touch her though, of course.

There are three doors in this corridor (including the one you came from) and two sets of metal bars blocking your way to the right. The third door is currently locked; you will need a red key for it. Enter the second door.
This room has 3 Slime enemies, 1 below and 2 above. Watch out for the height of the ceiling, as you can see on the map above, some parts of this room have higher ceilings than others. These will be the areas where it’s easiest to jump over the enemies if you wanna play it safe. Go all the way to the left, moving the wooden crate to the metal ones to reach the upper platform. There’s a moving platform between left and right, use that to get to the other side.
There’s only one enemy in this room, a Purple Succubus at the bottom. You cannot jump over to the platform on the right, so first you need to go below and get the crate to the metal stairs on the right to proceed. Make sure the succubus is turned away from you before starting to move the crate. Be quick, as she turns around relatively quickly. If she notices you, quickly go to the right as far as you can, she will lose you. If you wanna play it safe, you can move the crate a little to the right, hide in the wardrobe for one turn, and then move it again. On the right of the platform above the stairs, there will be a switch you have to turn on. This will open the metal bars previously blocking your way. Go back to Room 1.3.

Now we can go right to the newly opened area. Go down the stairs and enter the first door on the left.    In this room, there will be 3 moving platforms. Jump on the first one that goes diagonally to the left, then use the upper one to move to the right. There’s a crate on the right that we have to move to the upper moving platform. If you’re super quick, you can do it in one go, but it’s safer to wait for it to leave and then come back to push the crate on it. If the crate falls down, you’ll have to leave the room and come back to try again.
Once the crate is on the platform, wait until it goes all the way to the left, then push once it starts moving to the right. If you push it right, the crate should fall right down to the platform we need it to. Watch the minimap to get the timing right. Use the crate to climb the stairs, then enter the door.     There’s a switch puzzle in this room. You have to turn on all of the switches at once. Each switch turns on the switches next to it. Interact with the ones marked above in that particular order to solve the puzzle. If you did it right, you should see the “You hear something opening nearby…” text on your screen. This opened the second set of metal bars blocking your way. If you made a mistake, leave the room and enter again.
Go back to **Room 1.3**. Before going to the right, go downstairs and enter the 2nd door. Watch out for the Purple Succubus here.

There’s a save point in this room, so use it. For now, we cannot proceed in this room, so leave after saving. Go left to enter the 3rd door, however you will have to hide in the wardrobe once and wait for Purple Succubus to leave in order to proceed.    Once you’re in the next room, go immediately to the right and climb the stairs because there’s a new, **Green Succubus** enemy here. Reach the platform on the left by going above the succubus. Make sure to hold the jump button here to jump higher. Pick up the **Red Book** found on the metal crate then turn on the switch. This will activate a platform we need to proceed in the previous room with the save spot.    Go back to said room (**1.8**). Now we can use the moving platform and go to the left. This jump is quite big so be careful. If you fall down into the pit… rest in pieces. Enter the 1st door.

Be *very* careful in this room. There are breaking tiles on the ground (seen above as well) that may not be easily noticeable. You can tell the difference by looking at the image on the right.

The **Brown Succubus** will eat you alive here as well if you fall into the pit, so don’t. Be extra careful at the 4th breaking tile because this one is wider, so you will need to start the jump basically at the last pixel to be able to jump over. Thankfully, the last save point is near so if you fail you can just reload and try again.    There’s a Purple Succubus here and a **Red Key** that you will have to pick up. Go all the way to the left and enter the door.
You’re now back in **Room 1.8**. Climb the stairs, get the **Green Book**, then go all the way back to **Room 1.3**. Make sure to save on your way back at the save point.

Now we can go all the way to the right that was previously blocked by metal bars. There’s a locked door waiting at the end of the corridor and a Green Succubus in your way. You can open the door with the Red Key you previously picked up.    The next room is a safe room. Heal up if you need and save your progress. There’s also a **Blue Book** on the right of the save spot that you need to pick up. Once you’re done, go back to the previous room.    There’s another locked door here on the upper platform. Open that one as well with the same Red Key to enter the Library.

There are three bookshelves of varied colors in this room where you will have to place the three books you picked up. Blue book goes into blue shelf, green into green, red into red. Once you reach the bookshelves, a cutscene with the Green Succubus starts. Once it ends, you will have to be relatively quick to put the books in their correct shelves to open the way to the left before she catches you.    After leaving the library, don’t relax just yet. The Green Succubus will come after you. Don’t even try hiding in the wardrobe, she will find you anyway. Turn on the switch on the left and then go get the crate on the right. Push this crate all the way to the left, jump on it and then jump high up into the big black hole found in the wall to escape.
You’re now back in **Room 1.3**. Go all the way to the right to get back into the safe room, because the previous switch opened up the way forward. Make sure to heal and save before proceeding.    Don’t bother trying to jump up to the upper platform in this room because there will be a Brown Succubus here who is inescapable and runs pretty fast. Just get to the door on the far right as fast as you can and enter the next room. Keep running until the shining lift platform because she will follow you here!    Congratulations, you are now in the Dungeon area! This should unlock the **To the dungeons...** achievement.
## #2 - Dungeons

    The first room of the dungeon area is a safe room, so make sure to heal up and save. There’s also a bookshelf with some lore you should read.
The first door to your left is a puzzle room you need 3 items for, so let’s skip that for now (but you can go inside to check if you’re curious).

There’s a switch here that is currently turned on. DO NOT turn it off, unless you wanna get murdered by a lovely succubus princess in the next area. If you do, then by all means, turn it off, but don’t blame me. (Actually, I lied. For getting the **What's this one do?** achievement, you gotta press it, get caught, then reload.) Go into the leftmost room.    You won’t see her right away when entering, but at the end of this corridor is a **Red Succubus** enemy that is locked behind a set of metal bars, thankfully, because she is deadly. If you turned off the switch in the previous room, she will now eat you alive.
In the 2nd and 3rd room from the right, you will need the double jump, so you can skip those for now. Enter the 4th door.    There are two pressure plates here you will need to activate with crates. There’s one right next to the door, use the lower crate for that. Then climb the stairs on the right and push off the crate above. You need to push this crate onto the metal moving platform in the middle and use it on the pressure plate found on the left side. This will deactivate the metal bars and let you proceed. If you fall into the pit, there will be another Red Succubus anticipating your demise.    The next room will have another pressure plate puzzle and a new enemy, **Blonde Succubus**. Here, you will need to push the crate onto the moving platform when it’s going from left to right, so that when it reaches the hole on the right, the crate on it will slide off right onto the pressure plate below. If you push it on when the platform is moving from right to left, you will have to leave the room and re-enter to reset the puzzle. Once you’re done, you can take the elevator on the left to go downstairs and enter the bottom door on the right. Watch out for the Blonde Succubus.    In the next room, you will finally get the **Winged Shoes** (along with the Double Jump achievement) and also a **Stone Tablet** (remember the statue puzzle room?). Pick them up then proceed. You can now press the jump button two times to double jump. You will end up back in **Room 2.3**. Jump down and leave.    Enter the door on your right. This will take you to a pretty big room with some Blonde Succubi. Go all the way to the right while avoiding the rope traps on the ground. You will need to jump over the Blonde Succubus using the double jump if you don’t want to lose your virginity; it’s not the easiest maneuver, but it’s possible. You should jump right when she turns around. If you don’t care about preserving your V, just let her catch you and struggle out of her grip, she’s pretty weak. Push the crate found at the end of the corridor below the hole and use it to jump up a level.
There’s another crate here you will need to go one level above, so do the same. There’s also a Blonde Succubus locked behind bars whom you can set free by stepping on the pressure plate if you want to be killed. It’s your choice. Also, letting her out will net you the **Sweet Lies** achievement, so get that, then reload.

There’s some metal bars blocking your way to the right on the 2nd level, but that’s no issue, because the Red Succubus roaming around on the left will step on the pressure plate that opens it. Just stay next to the bars and proceed when she opens them for you. The Red Succubus on the left this time isn’t deadly, so if you don’t care about V and wanna see her scene, you can without dying.

There’s a save point on the top floor, so make sure to use that before proceeding. A chase scene is awaiting you behind that door; there’s a switch on the left that will make the scene easier, but I recommend trying without help first. Enter when ready.    Once you reach a certain point, a cutscene will appear and the game’s MVP, **Emi**, will make her first appearance. She’s the cutest succubus (don’t look at me, I’m biased) but god is she deadly. Start running as soon as the cutscene ends and try to avoid the rope traps on the ground. If you get caught in one, it’s not the end yet, but be fast. At the end of the corridor, there’s a pressure plate and a crate, quickly push the latter onto the plate to close Emi’s way with metal bars. Then proceed.    There’s a save point in this area again, so use it. Before leaving through the door at the bottom, you will need to pick up another **Stone Tablet** from the room to the right. You will need to avoid the pressure plates here because those will lock you in and immediately spawn a deadly Emi onto you, so be extra careful. Pick up the tablet then leave to the left. We are now back in **Room 2.6**. Go all the way to the left while avoiding the Blonde Succubus to get back to **Room 2.2**.
### Secret Switch #1

Before proceeding through the 3rd door from the left, now that we have the double jump, we will now backtrack to the starting area to get one of the secret switches. Go back to the 1st room, heal up and save if you need to, then take the elevator back upstairs. Go all the way back to **Room 1.15** then use the crate and the double jump to get to the door above.        There’s another super cute enemy in this room, the **Dragon Pup**, who, despite her name, is actually harmless, extremely shy and will run away if you look at her. You can see her peeking out from the wall waiting for you to leave. She will only come out if you pass by; you will need her help in activating the pressure plate to the right. To do so, just go past the pressure plate and stay by the metal bars WITHOUT turning around. Once she steps on it, you can proceed.

    The first secret switch is in this room. Ignore what the bookshelf tells you (of course she doesn’t want you to press the switch) and turn that bad boy on, then go back to the previous room. In order for Dragon girl to help you again, you will need to stand next to the metal bars and turn away so she doesn’t get spooked by you. Once she steps on the plate, turn back around and go through while she runs away. This will also net you the **Eep!** achievement.
Go all the way back to **Room 2.2**. Make sure to save on your way. We can finally go into the 3rd room.

### Secret Switch #2

    Use double jump to jump over the holes here. There’s a hidden room in the rightmost pit (as seen on the image) where we’ll need to get to for the 2nd secret switch, so fall down and jump into it. Go through the door.    Here, you will be welcomed by a new enemy, the **Kunoichi** (or Ninja). She’s super fast and super deadly. She will speak to you in a cutscene and will not hurt you just yet; save your progress then proceed through the door on the left, where you will have to survive a chase scene.        Start running left while avoiding the rope traps and the breaking platforms. Use the teleporter at the end to go to the next room. Here, just keep running. There will be a breaking platform at the end, but don’t avoid it, fall down and then immediately jump, there’s a secret hole in the middle you will have to jump into as seen on the map above. It may be a bit tricky to get it right, you can spam the jump button 3 times quickly to consistently be able to make it.    Use the teleporter. In the next room, you’ll have to avoid some rope traps, then use the teleporter at the end to enter another room with a switch. She will spawn in here as well as soon as you get the switch, so quickly teleport back into the rope trap room and avoid the rope traps again. After that, there will be a section with a new obstacle, sticky ground, that will slow your movements. Try to jump over it as far as you can and then you’ll be able to make it to the teleporter before the kunoichi catches you. Use the teleporter found in this room again.    In this last stretch, you will have to get through a sticky ground section by only jumping on the crates. The kunoichi will only spawn onto you if you step on the sticky, so don’t.    And now you are finally in the secret switch room. Turn it on, read Emi’s angry warning against it, then leave. Congrats, you managed to get through one of the hardest sections of the game! Good job! \*even Emi approves\* You will get the Kunoichi trial achievement. She will also praise you in a short cutscene. If you interact with her afterwards, you can get another scene with her. Save, and then go back to the room with the pit and take the elevator on the right one room above.    We are now in a big room with 3 doors, the 3rd one currently blocked by metal bars. Let’s start with the left room.    In this room, we need to deactivate the metal bars to turn on a switch on the left. Go to the top level and push off the crate to the left while avoiding the Blonde Succubus (you’ll need to hide in the wardrobe). Use it on the pressure plate to open the bars and then get down to get the switch. This will disable the metal bars in another room. Now leave, and go to the room on the right.    There’s a huge crate here that you will need to jump higher and reach the upper platforms. There’s a Red Succubus roaming around in the middle, who will step on the pressure plate that opens the metal bars on the top platform. You will need to go to the left while avoiding the Red Succubus, then wait for her to step on the plate to go to the top. Get the switch here, then leave the room.
The middle platform with the save point is now open. Make sure to save! You will now head into the first boss battle of the game!     A new enemy, the **Catgirl** awaits you here. She has two attacks: if you’re far away from her, she will shoot a homing heart your way that will charm you for a short period of time, and if you’re close enough to her, she will dash to you. When charmed, you’re not able to control the MC and he will walk towards the closest enemy who charmed him (in this case, Catgirl). You can escape the charm by struggling, but you will usually not have enough time before you walk right into her grasp, so try not to get charmed. You can jump away from the charming heart if you time it right, just before it touches you, but it needs to be super precise. She can also jump! So don’t think you’re safe just because you jumped on an upper platform. It’s usually better to let her catch you via dashing because that will only cause a footjob scene that you can escape from and it will not take away your virginity. If you walk into her while charmed, that’s more of an issue for your V, so try to avoid that.    There are a few obstacles you need to get through here, while also avoiding the Catgirl and her charms. First is the metal bars to the right; there’s no crate for the pressure plate here. You will have to use the Catgirl to open up the way, which can be a bit tricky. You’ll need to position her and yourself so that she’s coming after you from the left and you need to be close enough to the metal bars so that you can walk through before she steps off the plate. The easiest way to do this is to jump right up the small platform above (the first charming heart she shoots will dissipate before reaching you), wait for Catgirl to dash to the edge of the room beyond the door, then jump down and run quickly to the metal bars. If you do it right, she will step on the plate right when you are at the bars, letting you through.     The second obstacle involves two pressure plates and a switch. You have to jump on the middle platform, push the crate on the right on the pressure plate next to it, then go around to the other side of the platform and push the crate on the other plate, while avoiding Catgirl. This will open up the platform above where you have to turn on a switch. You can now proceed to the 3rd obstacle.    There are three switches you will need to turn on here in the order outlined on the image. Once that’s done, you can proceed to the right and after a while, the ground will disappear behind you, rendering the Catgirl incapable of following you. Congrats, you just beat the first boss of the game! Hurray! You’ll get the Outsmarted achievement.    In this room, you will find the 3rd Stone Tablet and a healing point on the right. Once you’re done with that, proceed to the left. This will take you back to Room 2.10. Save here, then take the elevator downstairs. Now we’ll have to backtrack to the statue room that opens from Room 2.1.    In the statue room, now you can insert the stone tablets in the correct statues for a door to appear that lets you proceed.    There’s a new enemy in this room, **Nightmare**. Watch out for her because she’s extremely fast. You can use the wardrobe to hide from her, then enter the door, since our way to the right is blocked for now.    You will arrive in a really long corridor with a switch at the end. Turn it on, then go back to the door, but be careful of the Nightmare in this room. You will need to go all the way to the left to turn on another switch. There will be a wardrobe to help you out here. After you’re done, go back to the previous room.        Now go right and enter the next door. There’s a pressure plate we need to activate here. Get the crate on the right and push it onto the plate on the left. It will open the way to the switch, turn that on then leave. Watch out, because now there’s a Nightmare patrolling this room.        You will arrive in an elevator room. Take it upstairs, and you will find yourself in the Main Area. You will get the **Main Area** achievement.
## #3 - Main Area

    You will end up in a pretty big room. Take the door immediately on your left to find a safe room to heal up and save your progress. There’s a new healing mechanic in this room; you can now ask the Catgirl to relieve you of your stored up pleasure as a way of healing. Note: this WILL pop your virginity bubble, however. So only use it if you don’t mind losing it.
Go back to the big room. Before we do anything, I’d like to warn you, that you may notice a red key lying on the ground in the middle left section. **Do not** just walk up to it to take it, because it’s a trap, and if you approach it, the ground above you will break and a Green Succubus will fall right on top of you, instantly draining you of your life. (Unless, again, that’s your thing, because then by all means, go for it.)

Make your way to the top right corridor, where you can find Clock Hands. We’ll need these to solve puzzles that will open the metal bars. Then go to the left side of the same level, use the hands on the clock, then go into the room at the end.    There’s a new obstacle here: poisonous gas. The game is kind and lets you know with a red colorization when it’s deadly, so you can easily know when to go through. (However, there’s a pretty nice scene if you die by these fumes, if you’re interested in that. It will take away your V, though.) Go all the way to the end of the corridor and leave. You can now safely jump down to get the red key without being surprised by a hungry Green Succubus. Make sure to leave this platform to the left and not the right for this reason.
Now go back to the top left section to get the **Clock Hands** so we can use it on other clocks. Open up the way to the bottom right section, while avoiding the **Green Succubus** here. **Be extra careful:** the first wardrobe is a trap! If you wait a little, you will see something (or someone) peeking out through the door. That’s **Closet Demon** and she’s deadly. Use the second wardrobe instead, that one is safe. Go into the room at the end.    You’re now in another pretty big area. There’s a save point here a level above, so make sure to use that before anything else. You can use the crate in the middle to help you reach the platform. There’s also 3 vases with 3 different colored roses here, that is a puzzle. We will need to get these three roses from the rooms in this area. To start, go into the room beyond the save point first.    There’s a new enemy here, **Pink Succubus**. If you want to get through here without popping your V, you have to go up, then down to get the switch and use the crate to go back upstairs before she sees you, as she has a very wide sight. It has pretty tight timing, so be quick, then leave.    Now go up a level. Use Red Key on the door here. The closet here is also a trap, so if you want to clear the room without the Pink Succubus catching you, you will need to jump over her, otherwise she will catch you. Get the **Clock Hands** on the left, then leave. (Make sure to save after each room.)    With the Clock Hands in our inventory, we can now turn off the metal bars here as well. Start with the one on the top right. There’s a poison gas + pressure plate puzzle here. Push the crate onto the plate while avoiding the gas to reach the **Green Rose** on the left, then leave.    Now go to the bottom right section. Don’t linger too much at the door in this room, because you will be surprised by a deadly Emi. Go into the second closet and wait for the cutscene to finish, then when Emi passes by, get out to get both the key and the **Blue Rose** at the end of the corridor. Quickly hide in the second closet again, then leave the room when Emi goes to check the third one. **Do not linger**, because she will come after you. Swiftly take the hands out of the clock to close the way. This will net you the **Now she’s really angry** achievement. Don’t forget to save.    Now we have 2 roses out of the 3 we need. To get the red one, we will need to go back to the first big room (**Room 3.1**). Here, open the way to the door in the middle right section. Watch out for the closet and just get the **Red Rose** on the left.
Go back to the other big room with the 3 vases (**Room 3.3**). Take a look at them, and make a note of how many roses you can find in one vase and of which color. Then, make your way to the middle right section to reach another big area.        You will find 3 empty vases here. The order in which you have to put the roses in corresponds to the number of roses found in the previous room’s vases. Which means that we will need to use the roses in this order: **Blue - Red - Green**. This will open the way to the right. In the first room, you will find a safe room; heal up if needed and save, then go into the second room.    In this room, you will find the **Megane Succubus**. She’s a huge bookworm and is pretty much only interested in books. She will not hurt you and if you bring her a book she likes, she will let you through. Read the lore on the bookshelf, then walk up to her to watch her cutscene. We will need to find that book, so let’s leave the room!
Back in **Room 3.9**, take the bottom right side corridor and go into the third room.    There’s a new enemy, the Vampire Succubus (or as I like to call her, **Big Tiddy Succubus**) here. The first 2 closets here are traps but the third one is safe. Use the moving platform to get into the room on the top right.    Use the crate on the pressure plate to get to the switch on the right, then go back to the previous room. Here, there’s a crate on the upper section, you need to push that off to open the way to the door on the right. The pressure plate is down below.    In this big room, you will encounter the **Imp Succubus**, who will challenge you to three trials in order to proceed. Follow her into the room on the right.    All you have to do here is not cum until the time limit is over. \*imp voice\* Easy, right? That basically means that she will start fucking you and you will have to keep struggling in order not to let the pleasure bar fill. Once you win, go over to the switch on the right, press it, then leave.
The switch has activated a moving platform in the middle. Use that to get to the room on the left one level above.    Here, as she will tell you, your task is simply not put it in for her. So you can just walk past her, get the switch, then exit the room. (Poor Imp though..........)    You can now get to the room on the right. Here, you will have to choose between a blue and a red pill. One will let you continue your adventure (**blue one**), the other… well, you can guess. Take the blue one and leave behind a disappointed imp who didn’t manage to make you cum. You will get the **Impish trials** achievement.
Use the newly activated elevator to enter the door at the top.

You are now in the library. Get through the Vampire to get the Dark Book at the end (this will be for our Megane Succ), and then go back all the way to Room 3.11, the Megane’s room.

Here, put the newly acquired Dark Book on the wardrobe next to her and she will let you through. Proceed accordingly.    Take the elevator here down to a brand new area.
## #4 - Moss Dungeon Area

    Woo hoo, new area! Don’t be so relieved though, this one is just as deadly as the others. There’s a save point you can use here, make sure you do, then enter the door on the left.        In this room, take the corridor on the bottom. Now, there’s a hole here. If you jump all the way down, you’ll end up in a pit with a loooot of succubi. They will all rape you, one by one. And you’ll die. If you wanna see that scene, go ahead. (Just don’t forget to reload.)    Otherwise, there’s a secret teleporter in the middle of the pit you will have to jump into. It’s similar to the jump in the kunoichi area, it may take you a few tries. Here, enter through the door (not the teleporter!)        Just go all the way, there are no enemies here. In the second room, you’ll find the Garden Key. Pick that up, then go back.
Now, however, you’ll need to watch out, because a new enemy has spawned, the **Kissing Succubus**, who is inescapable. You’ll have to go back to the room with the key and hide the closet, then leave to avoid her. Once you’re back in **Room 4.2**, you can now take the top level to proceed.    A new enemy, the **Mummy** awaits you here. She’s blind, so she will only catch you, if you run into her. Here, you will also find a new obstacle: sticky ground. On spots where you see purple slime, your speed is reduced so watch out. You will have to take the route on the bottom, avoiding the Mummy as you reach the end, then get on the platform above and push the crate to the right so you can use it to jump even higher.    Go all the way to the left and jump down, but watch the minimap as there are Mummies down there. You will have to go left, but the floor is sticky and there are two Mummies roaming around. The first closet is a trap, but the second one is safe. Enter the room at the end.    Here, you will need to get the **Blue Key** and a code found on the left side. Make sure to wait until the Mummy goes past the jumping hole to the right before proceeding, otherwise you won’t have a chance to move around her. Get the key and the code, then leave from where you came from.    Oops! Looks like you fell into a hole. Don’t worry, it’s intended. Use the save point, then proceed. There will be 2 Mummies in your way; you will have to jump over them to avoid getting fucked.    Go over to the right platform to get a crate. Push it down one level below to open the metal bars to the left. Then go to the newly opened path and get through the 2 Mummies to pick up the **Clock Hands**.
Proceed to the right where you used the crate for the bars. Use the clock hands on the clock, then jump down, watching out for the Mummies.    First, you will have to turn on the switch on the right beyond the Mummy. Then go left, and go back for the previously used clock hands to use them on the clock below so you can proceed.    To the left, there’s another Mummy and another switch to press before going back all the way to the top platform. But before you do that, get the clock hands back from the bottom clock to use them again on the top one. Jump over the big hole to the right (it may help falling into the hole first and then jumping out) and then exit through the teleporter at the end.
You’re now back in **Room 4.1**. Save, heal if needed, then open the door with a triangle symbol with the Blue Key.    Here, go through the first door. It’s puzzle time! You will have to go through the correct doors in the correct order to avoid the Succubus Lord sucking you off. If you want to see her scene, just exit the door you entered and you’ll get it.
Otherwise, follow this order:

Left door -> right door -> middle door -> middle door    Now you’re in a room with a new enemy, the **Troll Succubus**. Immediately hide in the second closet (first one’s a trap) because she can see the entire room, so when she turns around, she’ll catch you. Get the switch puzzle solution (11001101) from the bookcase, then exit. Press the switches based on the solution (1 means on, 0 means off) to proceed.    In this big area, you have to take the moving platform to go around. The Mummy in the middle will step on the switches that will open the metal bars, you’ll have to time it right. In the pit, a Troll is waiting for you, so don’t fall in. Enter the door on the right.    Here, pick up the **Old Key** and read some lore, then go all the way back to **Room 4.1**.
Now, with the Old Key and Garden Key in our hands, we can go back to the Main Area.    Go back to **Room 3.9**. Here, we will need the Garden Key in the first room on the bottom right side. Go in, then open the locked door with said key.
## #5 - Gardens

    You are now in the gardens! You’ll get the **Gardens** achievement. This is an optional area, but it would’ve been sad to miss it as the best enemies are all found here (that’s an objective fact). (Also not-so-optional if you wanna get all switches, but yeah.)    If you start going to the left, you’ll have to watch out because there IS an enemy here (one of the bests), the **DARK ELF**, except she’s invisible. (Well, not completely, of course, if you pay attention, you’ll be able to see her.) Avoid her, then save at the save point before proceeding.
You’ll need to get the Shed Key to get into the little house, and the Labyrinth Key to go through the big gate. Go all the way to the left to enter a new part of the Gardens.    There’s another Elf here, so watch out. And then another one above. And then, you’ll have to do some platforming, otherwise you’ll fall into the pit with a never-ending supply of Alraunes (another one of the best enemies). She’s super cute, so I’d fall down just to watch her animation. Just sayin’. Your choice.
Once you’re through, get the **Labyrinth Key** at the end before going back to the previous screen. There’s an Elf here, too, so watch out.

Use the Labyrinth Key on the big gate next to the save point (save first) to enter the labyrinth.    Once you enter, there’s a cute (but deadly) Alraune on your right, and two doors on your left. Take the **first one**.
In the next section, take the **door on your left** (the only one you can take, really).

Then, take the **third door to your right** while jumping over the Alraune.

Here, pick up the **Shed Key** and then follow the same route back outside.

Now we can go into the Shed!

### Secret Switch #3

    You found the third and the last secret switch! Here, get the switch on your left while watching out for the Elf walking around the room. She walks across the whole place, so make sure to jump over her when the time’s right, then exit. Getting all three switches will net you the **Secret Switches** achievement as well.
We can now go all the way back to the Main Area, **Room 3.9**.

## #6 - Main Area part 2

    Back in **Room 3.9** after exiting the garden room, before going into the room to your right, go back to the middle and use the Old Key on the left keyhole to open up the path to the upper left. Go into the first room.    This room is the Donation Room. If you’re still a virgin, the **Head Nurse** will tell you that you can donate your sperm to the Nurse at the end of the corridor. Otherwise, she will ask you to leave. Donating your sperm will not kill you but it will take away your virginity (obviously). So if you want to get the true ending, save first, watch the scenes, then reload. Also, there’s a hidden scene in this room. If you keep bothering the Head Nurse, you can fuck her, too. You’ll need to talk to her 3 times for that. (But she will also only let you touch her if you’re a virgin.)    Once you’re done, go back and enter the door to the left, beyond the donation room. Use the teleporter here, then the one on the left.    Avoid the Troll and use the teleporter on the right. Get the switch, teleport back, then use the other one.
Here, push the crate down, then go back all the way to the room with 3 teleporters. Use the middle one to go back. Now the metal bars are disabled so you can proceed.

Use the previously pushed down crate on the floor switch to open the metal bars. Enter the door.    Woo hoo, you finally found your sister! But… something’s wrong with her, and now she wants to desperately fuck you. Stays in the family, I guess. (Thankfully, it’s not like you’re blood-related.) You’ll get the **Reunion** achievement.
After the cutscene, you’ll have to survive a chase scene. First, jump over her and go into the room on the left.    Here, you will need to watch out as the sis can randomly teleport closer to you and if you’re not careful, you can get stuck in a corridor where you cannot jump over her. Follow the order on the screenshot in which you’ll need to get through the obstacles here.    Get another **Old Key** in this room, then leave. The sis will not follow you here anymore.    You are now back in **Room 3.1**! Use the safe room here to heal up and save, then take the bottom right corridor. We’re now back in the big area with the rose puzzle, you can use the middle right door to get back to **Room 3.9**, where we can use the other Old Key.
Now back in Room 3.9, save first. If you wanna see a super sexy scene, go to the corridor with the nurse room, and enter the door at the end with the sign.    Here, the Imp will be waiting for you with a charmed Catgirl and they will both rape you at once. Mhmmm, yummy.
Okay, let’s get back to business.

Note: if you want to get the achievement for beating the game while staying pure all the way to the end, make sure to create a separate save file here, because we will be losing our V. You’ll need to reload this and beat the game again from this point to get that achievement.

After that, take the bottom right section of the room and enter the 2nd door, the one after the gardens one. You can only get past here, if you’re still a virgin; otherwise, the **Beast Girl** in the next room will eat you alive. If you’re not a virgin, leave. (And this way, you will not be able to get the true ending.) Also, even if you’re a virgin, but you haven’t followed this walkthrough thoroughly (tsk, tsk) and didn’t get all 3 secret switches, there’s no way to get through.    If you check all the boxes, just walk to the end of the corridor and enter the door at the end. You will encounter the Beast Girl along the way, who will barely spare you a glance if you’re untouched and let you through without an issue. You will also get the Doggo achievement for witnessing a calm doggo.    In this room, if you haven’t pressed all 3 switches, you will find three metal bars blocking your way like on the screenshot. But we came here since we got all 3 (right?), so we can just proceed.    Take the elevator on the right end to get to the secret dungeon.    Go to the right to enter the room at the end. You can read Emi’s very angry GET OUT!! warning and just outright ignore it to proceed.    You will end up in Emi’s private room. You can also find the cutest thing here, **Lizzie the lizard**, her pet, just chilling on the wardrobe. What’s a bit more interesting is that you can also get your hands on Emi’s diary, where you can learn a little bit about what has been haunting Emi ever since she’s been turned into a succubus. This will also get you the **Her name is Emi** achievement. If you proceed, Emi will appear and (obviously) try to kill you. Exit the room on the right and start running.    You will find yourself in a long corridor with a bridge in the middle. If you run past, there’s a switch you can press towards the end that will lower the bridge and cause Emi to fall, barely hanging onto the edge of the platform.
Here, you actually have a choice. You can go to her and pull her up, or just leave her there to rot.

(But even if you help her up, she will still fuck you, ‘cause that’s who she is. She’s not a monster, though, so she will spare you and you will wake up in the same spot she left you.)

Choose to help her to get the true ending, you can leave this room on the right and go all the way back to **Room 3.9**.    We can now use the Old Key on the right keyhole to open up the path.        Go past the Troll Succubus, go up to the top level, because there’s a save point there. Save, then return to the room one level below.
There’s a puzzle in this room. If you read the two signs, you can notice that it says Observe your environment… and its mirrored version. This basically means that the room itself needs to be mirrored. You have a time limit to achieve that as there’s poisonous gas coming from above. You can see how much time you have left by paying attention to your Pleasure Bar. (However, there’s a really sexy scene with the Megane Succubus if you die before you solve the puzzle. So you could watch that first.)    Use the image above to solve it. You’ll need to push the crate to the same position where it is on the left. Don’t push it too hard, otherwise the crate can get stuck on the small platform above the ground that will softlock you. (But if that happens, just die and restart.)
Once you’re done, the eerie music will stop and you can get to the right section where you can pick up the **Red Gem** and turn on the switch. Exit the room.

Save again (this is IMPORTANT!!!), then go down a level and enter the room there.    So this room is one of the trickiest parts of the game (in my humble opinion). Here, you will need to get to the other side of the room while avoiding charm kisses the **Dark Succubi** throw at you. Also, there’s a deadly Brown Succubus waiting for you in the pit like usual, so if you get charmed and end up down there… bad news for you.    Once you’re through, your turmoil isn’t over. Here, there are 3 Dark Succubi again and 2 of them are deadly. You’ll need to avoid their charm kisses and get the **Blue Gem** in the middle of the pit.
Aaaand then you gotta go all the way back. Good luck!    With the two gems in our hands, go to the top level and put them on the pedestals. The red goes on the right pedestal, the blue goes on the left. This will open the metal bar and let you proceed to the final boss: Succubus Lord. Make sure to save beforehand!
You will arrive in her room where there’s a **Mansion Key** you have to pick up. It may seem as if she doesn’t care about you, but when you try to leave, she will obviously not let you go and instead you’ll be teleported into a big area.        You have two lives with the Succubus Lord (in Hardmode, she kills you immediately), if she catches you the third time, that’s deadly. She has two attacks: when she flashes in white color, she will dash to your position. You can easily avoid this if you just keep moving and don’t stop, because she will teleport to the position you were in when she stopped flashing.    When she flashes in a red color, instead of dashing to your spot, she will reappear at your spot and make a slow dash from left to right. You can avoid her if you stop in your place when she disappears after the flashing, then jump over her to the left when she appears next to you. Or, alternatively, you can just start running to the right when she appears because she’s not faster than you are.
Note: in Hardmode, she has a third attack. When she flashes purple, she shoots out a charming heart to your position. You can also easily avoid this if you just keep moving.    Now, with that out of the way, what you actually need to do here is get the switch in the top right corner. To do so, we’ll need to get through some obstacles first.
There’s a whole in the middle of the room. We’ll need to fill this hole with two boxes so we could push a third one through.

First, push the bottom crate next to the middle left platform and use it to get there. Push off that crate into the hole, then go to the top left section and push that crate into the hole as well. It’s actually a good idea to disable the traps, makes the run easier, just make sure not to get trapped when the Succ Lord is doing any of her attacks.

Once you filled the hole with two boxes, go back for the first one and push it to the other side, next to the middle right platform. Get the switch on the right, then use the crate to jump and get the 2nd switch. Once you’ve done that, you can leave the room.

It’s not the end yet, however. Now you’ll have to run back all the way to the big Mansion Gate, through room 3.33, which is now filled with traps. While you’re on the stairs, just keep running because here she will only do the dashing attack. But once you’re down on a solid level, she will do her red attack, which you will need to avoid NOT on the stairs (it’s probably possible to avoid on the stairs, too, but it’s MUCH harder).

Once you’re out of the room, just run all the way to the Mansion Gate and it’ll automatically open.

Congratulations, you’ve beaten the final boss of the game! You will get the **Lord of the Mansion** achievement.

You’re out of the mansion! Start going to the right as long as you can. After a while, you will be stopped by an appearing Emi, who will just simply let you go. You can freely leave.    You will look at the succubi infested mansion with outrage until a strange girl appears from the forest. She says her name is Erika and that she can make you stronger, strong enough to fight the succubi.
And that’s it for the true ending! The Freedom…? achievement is now yours.

Hope you enjoyed the game and that this guide was helpful!

If you wanna get all the achievements, we have 3 remaining:

**Almost got away…** - this is the normal ending. You can get this if you don’t help Emi after she falls down in her scene, or if you just don’t go into her room at all. It’s good to combine this with…

**Pure** - …the achievement you get for beating the game while staying a virgin all the way until the credits roll. If you go into Emi’s room and do her scene, she will take your virginity all the time, so you need to skip that.

**Hardcore** – you can get this by beating the game in Hardmode. You can enable that at the very end of the tutorial.
