The Backdoor

<choose>,
<option></option>
<option></option>
</choose>The Backdoor is a sub-floor that can be accessed from a side door in the exterior of the Lobby, or through the "Create Elevator" Menu. As of March 30th, 2024, The Backdoor is only enterable if players have previously obtained the Detour achievement from entering The Rooms.
The Backdoor was initially released on March 15, 2024 for the 2024 Roblox event, The Hunt: First Edition, where it awarded players the "THE HUNT - First Edition" achievement and a badge for the event. The trailer was uploaded to YouTube 1 day prior to the event. After the event concluded on March 30, 2024, the sub-floor remained in the game, although its entrance was changed, and also rewarded 2 different achievements, making "THE HUNT - First Edition" achievement unobtainable. 
== Overview==
The Backdoor entrance can be found by exiting The Lobby via the front doors, taking a right, and proceeding until a player reaches an opening in the gate. If a player has not entered The Rooms yet, a glowing Curious Light themed barrier will be seen blocking the opening and text will appear stating that players need the Detour achievement (which is obtainable by entering The Rooms for the first time) to proceed. Behind the gate is a door acting as an elevator, which holds up to four players. During The Hunt: First Edition, players could've instead accessed The Backdoor by entering any of the elevators in the once-barricaded corridor in The Lobby, which contained a sign which explained how players could've obtained "THE HUNT: First Edition" achievement.
The Backdoor contains its own cast of unique entities, with similar, yet different ways of attacking players compared to the entities that are found within the Hotel. Drawers can be found throughout The Backdoor, and may contain Gold, Room Keys (in rooms with locked doors), or Vials of Starlight.
Closets and Timer Levers also appear throughout The Backdoor. 
The Backdoor features a unique timer mechanic. Once players open Door -50, they will be given one minute to complete the entire floor. The amount of time players will have to complete the floor can only be increased by players interacting with Timer Levers, which appear randomly throughout The Backdoor, and will add either 30 or 60 seconds depending on the time remaining when the lever spawns. Door -50 will always have a Timer Lever. The amount of time players have remaining can be seen above Timer Levers and on the front of each opened numbered door. 
As players' remaining time decreases, the background music changes accordingly, becoming more intense and frantic. If players run out of time, Haste will spawn and begin chasing them, killing any players it reaches instantly. Haste will disappear immediately if players pull a Timer Lever before it succeeds in killing them.
The Backdoor's appearance is similar to The Hotel, with the most noticeable differences being that The Backdoor has lightbulbs instead of wall lamps, brighter lights and a different wood for its interior.
The final door, -01, contains the Bottle of Starlight, which players can purchase for 100 gold, as well as a Timer Lever that provides 30 extra seconds. 
Another numbered door, 0000, is located at the back of -01. Once any player interacts with it, a cutscene will play where the door will shatter into pieces, revealing a yellow glowing portal behind it. Then, all players (including those who are dead and spectating) will be granted the "Other Way Around" achievement (or "THE HUNT: Escape The Backdoor" if it's before THE HUNT event ended), if they do not own it already. After a 15-second skippable intermission, all players will be teleported to The Reception with the use of a ancient rock portal, and will be able to continue their run in the Hotel. Players will retain their remaining health, and any items in their inventory, but they will not be able to use the Pre-Run shop.

Blitz=
<choose><option></option>
<option></option>
</choose>
Blitz is a hostile entity that appears in The Backdoor.
== Appearance==
Blitz takes on the appearance of a distorted green face, similar to that of Rush. Its face turns pink and distorts further when rebounding, with wider eyes and smile, while still having a small green "aura." When crucified, Blitz will repeatedly switch between its rushing form and its rebounding form.
== Behavior==
Blitz has a behavior nearly identical to that of Rush’s; when Blitz spawns, the lights in the current room will flicker to indicate its arrival. It will rush through and attack all players in its line of sight while producing a distorted screeching sound. This attack will deal fatal damage to targeted players, though those under the effect of a Vial or Bottle of Starlight may survive the attack.
Unlike Rush, after passing through all rooms, Blitz has a chance to turn pink and rebound, similar to Ambush. Blitz can rebound multiple times before leaving, depending on the time left, although most commonly, it will rebound only once or twice.
Unlike Rush, Blitz will not open the door to the next room.
Blitz will never rebound if the timer is below 30 seconds.
== Strategy==
Because Blitz acts nearly the same way as Rush, hiding in a closet will guarantee a player's survival. Similar to Ambush, players should be cautious of Blitz's rebounding until its screaming sounds can no longer be heard. This is because Blitz can still rebound after passing through the next unopened door.
Players who are avoiding Blitz can hide inside a closet for as long as needed due to the absence of Hide in the Backdoor. If a player cannot find a closet in time they are able to use a Vial to survive the attack or find a safe spot. Note: This will only work if the player has more than 80 health points, otherwise they will not receive the extra health buff.
== Trivia==
*The decal name of Blitz's green appearance is "rushs brother LORE LORE LORE".
**Similarly, its pink appearance is named "rushs sister LORE LORE LORE".
*Blitz is "lightning" in German.
*Before deciding on a final name, Blitz was referred as "Grush", a portmanteau of Rush's name and the color green.
*Similar to Rush, it is possible to hide from Blitz without entering a closet. A player can enter a side room (that is not occupied by the Vacuum) and hide behind a wall to survive.
**However, players cannot unlock the "In Plain Sight" achievement via this method. This is likely an oversight by DOORS' developers.
*Because Blitz is Rush's counterpart, all of its sounds are Rush's but sped up. 
**The sped up sounds are really similar to the SUPER HARD MODE rush clone audio cues.
***It is the only Doors entity to share the same jumpscare audio from another entity (which is Rush's but sped up).
*Whenever a player dies to Blitz for the first time, Curious Light says "She said we should call that one Blitz." It's currently unknown who 'she' is. Though currently unconfirmed, 'she' may be The Guiding Light.
*Blitz uses any pronouns. Q: whats Blitz pronouns A: any -Lsplash, Twitter

|-|Lookman=
<choose>
<option></option>
<option></option>
</choose>
The Lookman is a hostile entity that appears in The Backdoor.
== Appearance==
The Lookman takes on the appearance of a tall, shadowy humanoid silhouette similar to Shadow, but with glowing white eyes that turn purple when looked at. When crucified, The Lookman distorts, and its eyes become red and widen drastically, while also looking slightly upwards.
== Behavior==
The Lookman behaves similarly to Eyes because the whole character is a reference to the beta version of Eyes, with the same name and design. The only difference is that the Lookman damages a player once, then teleports to a different position. Furthermore, its audio cues are very quiet, making it difficult for players to detect the presence of the Lookman.
 
It has a chance to spawn in most rooms and makes a low rumbling noise. If players look at its eyes, it will attack them, briefly darkening their vision and teleporting to a random place in the room while making a thumping noise and causing the lights to flicker. The Lookman will despawn when the next door is opened. 
== Strategy==
The Lookman only attacks if players look directly at its eyes. Thankfully, the Lookman has a tall stature and thus can be easily avoided by looking down slightly to avoid eye contact.
The Lookman has a tendency to spawn close to the exit door of a room. Players can use this to their advantage and save time by listening for its rumbling cue when in rooms that have multiple possible exits, such as the Maintenance Hallway rooms, and it is especially useful in navigating dark rooms. However, players will lose this navigational niche if it teleports away to a different location.
== Trivia==
*The Lookman's design is based off of Eyes' original design.
**The Lookman's name is derived from an older version of Eyes' name. "also, 'Eyes' was originally called 'Lookman'" -LSPLASH, Twitter 
*The Lookman is the third of four entities featured on the DOORS icon, the second being Dupe, the first being Seek, and the fourth being the Gloombats.
*The Lookman, like Eyes, can't hurt players while hiding.
*The Lookman 's design looks similar to Shadow, though this is probably a coincidence.
*When dying to the Lookman when spawned by Candy in the Hotel or Mines using the Trick or Treat Modifier, there will be no death message, despite death messages being present when the Trick or Treat modifier is active. 
**Theoretically, this would happen due to the fact that Curious Light isn't present at the Hotel.

Haste=
<choose>
<option></option>
<option></option>
</choose>
Haste is the main antagonist of The Backdoor, and acts as a time limit.
== Appearance==
Haste takes on the appearance of a red human skull with black, hollow eyes and a grainy 'skin' texture. Its' colors are similar to that of a spectrogram image. When crucified, Haste's mouth opens wider. Its' 'body' stretches and distorts during the process.
== Behavior==
Haste will spawn when the Backdoor's timer runs out. It will highlight a player's screen with a red haze and begin to approach from behind, killing a player instantly if caught. If a Timer Lever is activated to increase the time during Haste's attack, it will immediately despawn. Do note that you can know how close Haste is to players by looking backwards, as you can see Haste through walls.
== Strategy==
Haste requires the most attention out of any entity in the Backdoor. Players who do not look for or do not activate levers can very easily be killed by Haste. It is important that players keep an eye out for hidden Time Levers, such as those in side rooms and out of plain sight, and prioritize their time both progressing through the floor's rooms and collecting gold and items.
Even if players are being targeted by Haste, they may still find Timer Levers by exploring rooms to extend their time. Any extension to the time by activating a switch will immediately despawn Haste.
== Trivia==
*Haste is a reference to Specimen 9 from Spooky's Jump Scare Mansion. Both are red skulls, have near identical death screens with repeatedly-displayed mantras ("TO TAKE THE DEAD" and "NO TIME LEFT" for Specimen 9 and Haste respectively), both kill players in one hit, both can be seen through walls, and both appear under specific circumstances related to time.
*It may be a reference to THE END IS NEAR signal from Voices Of The Void. The skull looks more similarly to the VotV variant, rather than SJM one.
*Haste's near sound bares similarities with Siberia Hell sounds, accompanied with streamer IShowSpeed screaming when it is near.
*Haste was planned to be added to DOORS since September 2022 but was scrapped.
*Haste is the loudest entity in DOORS.
*Haste's original mechanic was to attack players if they stalled in a room too long, forcing them to hide. The developers thought the mechanic made no sense, so the entity was shelved.LSPLASH on X: "@OGNface 3. after stalling in a room for too long it chased down players and made you hide... which fundamentally made absolutely 0 sense whatsoever, so it was shelved" / X
*Similar to A-90, Haste is a client-sided entity, meaning there will be a unique instance of Haste for every player.
**As a result, players who are dead and spectating the game will not see Haste and any of its effects.
**Despite Haste being a client-sided entity, exploiters aren't able to bypass the time limit by disabling Haste on their client.
*If a player were to be killed by Haste during the intermission whilst returning to The Hotel, they will still be able to exit normally but will lose any items they had on them.
*Haste's jumpscare sound consists of the default player death sound being played repeatedly.
*Curiously, players can still interact with time levers during Haste's jumpscare. This will despawn it and players won't die.
*Before The Hunt event ended, when Haste was on your screen and it says "NO TIME LEFT", you were still able to move for a couple more seconds before Haste actually kills you.
**After The Hunt event ended, if Haste reaches you fully and on the screen it says "NO TIME LEFT", you are no longer be able to move.
*As of the Content Update, it is now possible to crucify Haste using the Make Haste modifier.
**This will reset the timer to 1 minute.

Main Article: Curious Light
</choose>
Curious Light is a mysterious yellow aura and death messenger entity in DOORS, appearing in The Backdoor. It is one of The Three Architects and its main purpose is to provide somewhat helpful messages after death, on top of highlighting areas of progression. 
== Appearance==
Curious Light resembles the Guiding Light, claiming the simplistic appearance of a downpour of rain, the only difference being the slight yellow hue of its color.
It can be further identified by its unique soundtrack, being a much more quiet and somber version of Guiding Light’s, hinting at a possible affiliation between the entities.
== Behavior==
Curious Light can be seen after dying in The Backdoor (or The Rooms) or when lighting up one of the naturally-spawning exit doors. It attempts to provide tips on surviving the entities but does not provide the same level of clarity as Guiding Light, seemingly stating the obvious or nothing substantial at all.
Unlike the Guiding Light, Curious Light does not actively light up dark environments, being only present in the Death Screen, only lighting up certain doors, or while making shimmering noises when a player is near a Room Key.
The Curious Light has its limits with players as dying numerous times to a specific entity in the Backdoor will cause Curious Light to slowly lose its patience, going as far as to sarcastically congratulating a player for dying to the Vacuum the fourth time.
== Trivia==
*The Curious Light's name originates from a soundtrack by LSPLASH.
*Curious Light's color and sparkles can be seen at the end of The Backdoor, indicating that Curious Light is technically also in the Hotel.
*It has been confirmed that the Curious Light will play a bigger role in the overall game in the future.Q: "Will we be getting lore behind curious and guiding light?" A: "yes! major plans for them" -GhostlyWowzers
*The Curious Light theme is pretty similar to "Last Breath" from Ultimate Custom Night and Guiding Light's theme.
*According to Curious Light's line, "Look around for the levers I placed for you," it is responsible for installing the levers found in The Backdoor.
*At some point, Curious Light was not alone, as it was told by an unknown entity with feminine pronouns that it should call "that one" Blitz. The identity of this entity has not been confirmed, although it may be Guiding Light.

Glitch=

Main Article: Glitch
</choose>
Glitch is a pivotal and mysterious entity in DOORS, residing in the Hotel, The Rooms, and The Backdoor. It acts as a failsafe for players if a room fails to generate correctly as well as teleport players who are lagging behind back to their group.
== Appearance==
Glitch is a distinct dark-purple-colored humanoid similar to Seek, with multiple purple cubes and protrusions sticking out of its body. It passively emits an aura of pixelated and colored squares around its body. 
== Behavior==
Glitch is a failsafe implemented to ensure players can progress if room generation fails; for example, when a new room overlaps with a previous one. It appears on players' screens and sends them to the next room, without dealing damage. All rooms behind the new room are then unloaded to fix the issue. It will indicate its approach by producing glitch effects on players' screens and closing all opened doors.
In The Backdoor, Glitch also teleports players who are 4 rooms behind the leader back to their group.
== Trivia==
*Glitch was non-canon before the content update "glitch is non canon so it can do whatever you want it to" – RediblesQW, Twitter "this update was our way to canonizing glitch im glad you mentioned that cause i wanted to make a tweet about it" – RediblesQW, on cheddar balls video named "Glitch's Lore Is ABSOLUTELY CRAZY! (Doors CONTENT UPDATE Lore / Theory)"
**The Guiding Light said it didn't know who killed a player if Glitch teleported them to the group. However, this message was removed in the Hotel+ Update and the statement was seemingly retconned when El Goblino claimed to have seen someone that looked similar to Seek, but purple and weird, inferring it encountered Glitch. However, it was confirmed that this will be updated for consistency with what is canon to DOORS.Q: "El goblino mentions something like seek but purple and weird. Glitch fits the most, but Glitch isn't canon. Does this mean theres a new entity?" A: "it'll be updated as to not have any inconcistency" — WowzersItsMe
**It is possible this has already been updated and Glitch being canon, as the dialogue from El Goblino has been updated to refer to Seek as "That eyeball guy" rather than removing the possible mention of Glitch.
*Glitch will always turn player's camera to face it when encountered.
*Prior to the Hotel+ Update, Glitch also teleported players that lagged behind in the Hotel back to the group and dealt 10-40 damage when doing so. This function has now been given to Void. 
**Ironically, this was Glitch's original purpose. The room generation failsafe functionality was added later on.
**However, Glitch can still teleport players who are behind in The Rooms or The Backdoor or falling out of the map into the void.
*Glitch is the only entity to appear in every Floor. This might have something to do with the fact that it is non-canon.
**After being turned canon it might be because it can follow the players and it might be stronger than, or can go undetected by The Architects.
*Glitch can jumpscare twice in a row.
*Despite popular belief, Glitch cannot kill or damage players. (After Hotel+)
*In the Tower Heroes Event, Glitch seems to shapeshift into/possess other entities, albeit still showing its glitch particles.
**It is probably only capable of this because because both it and the Tower Heroes Event are non-canon.
***With the release of the Content Update, it is possible that the glitch fragment intentionally parallels this behavior, though it is only speculation as of now.
**This also may be tied to its glitchy nature, as many popular glitches involves characters being where they aren’t supposed to, or messing with the appearance of a character.
*Glitch is taller than Figure.
*Glitch changed the release date of The Mines from January 2025 to August 30 2024, causing people to mention that it "saved" them from waiting more time.

== Hazards==
<tabber>
Vacuum=
{|class="article-table" width="100%" ! 
|-
|
The Vacuum is a major hazard in The Backdoor.
== Appearance==
The vacuum's exterior appears to look like a regular door, indiscernible from the outside, similar to Dupe, though it differs in the fact that its interior appears to be a hollow vacuum, which, as described by Curious Light, "has no oxygen." The vacuum presumably surrounds the entirety of the Backdoor. It is unknown if it could also surround The Hotel although it is unlikely as there is a courtyard and rain on it. Also, given the existence of the Mines and the Castle, this seems to be a feature exclusive to the Backdoor.
== Behavior==
The vacuum is not openly hostile, and is only triggered when one opens a side door of one of the rooms. Upon doing so, the vacuum will start pulling nearby players toward the door, and if entered, they will be instantly killed. Players can still walk away from the door before getting sucked in to escape. The way to detect Vacuum is by looking at the screens, if the door has a screen then it is real, if it does not then it could be a door with Vacuum.
In addition to the vacuum doors, some rooms may have a giant hole in them, exposing players to the vacuum. However, players cannot die from the vacuum from these holes as there will always be objects preventing the player from being sucked in.
== Trivia==
*A line of the Curious Light's dialogue saying "...[The Backdoor is] somewhat forgotten, too. Some parts seem to be missing entirely." seems to imply that the doors leading out to the vacuum were created as a result of parts of the Backdoor being "forgotten". It is currently uncertain what the word "forgotten" means in this context.
*The vacuum is thought to be based off of Dupe and Subspace Tripmine in some fashion.
*The vacuum may also be possibly connected in some way to Void, though this is purely speculation.

== Room Mechanics==
===Guaranteed Rooms === 
*Door -51, Storage Room
*Door -50, Two Gates Room
*Door -01, Bottle of Starlight Room
*Door 0000, Entrance to The Reception
===Locked Rooms===
Locked Rooms require a Backdoor Room Key to progress into the next room. The required Room Key may be found in or on top of drawers or on the floor. 
===Dark Rooms===
Occasionally, rooms may spawn without any light, accompanied by a mysterious sound cue (similar to the one present in the Hotel). However, unlike the Hotel, there is no entity (e.g. Screech) that spawns exclusively in dark rooms. This only causes a visual hindrance.
===Timer Lever Rooms===
Rooms that contain a Timer Lever, which can be activated to reset the timer of Haste spawning. They can be found in normal rooms or in side rooms. 
==Special Locations==
===Entrances===
====Elevator (Removed)====
Before The Hunt: First Edition ended, when starting a run, an Elevator teleported players to Room -51. It opened itself once all players have loaded into the game and closed automatically. This Elevator did not feature the Pre-Run Shop, and the song Elevator Jam did not play. Whilst in the Lobby, the elevator doorframe had a blue outline, the same as the event area entrance, as that was the brand color for the The Hunt: First Edition event. 
====Backdoor Entrance==== 
At present, provided they have the Detour achievement, players can go outside the Lobby's doors, take a right, and pass through to enter The Backdoor. Once players are loaded in, they appear just on the doorstep of the Lobby's backdoor. The door will shut after a few seconds, like the Elevator. Similar to the elevator, it does not feature the Pre-Run Shop, and the song Elevator Jam does not play.
===Room -51===
Room -51 is the first room in The Backdoor. Tables, drawers, closets, and decorative boxes may generate within the room. A Room Key generates on top of a table or set of drawers behind a fenced-off corner. Players must crouch beneath the fence and collect the Room Key to progress to Room -50. This is the only room in The Backdoor where there is no time limit, as the timer does not start until the door to Room -50 opens.
===Two Gates Room (Room -50) ===
The Two Gates Room, or Room -50, is guaranteed to be the first room to generate after Room -51. The Two Gates Room consists of two gates (one of which may be closed), with a wall running between them. A Timer Lever is attached to the front of said wall, and upon a player interacting with it, one minute will be added to the in-game timer. 
The Two Gates Room after Room -50 can reappear, however it usually will have a difference (such as a lack/different position of a Timer Lever, or one of the gates may be opened or closed). 
===Room -01 ===
Room -01 is the final room in The Backdoor. This room will generate a Timer Lever next to the entrance. The room's centerpiece is the Bottle of Starlight, which floats above a pedestal surrounded by a pile of bricks. Players can purchase it for gold. There is a staircase on each side of the pedestal, leading to a raised floor. Door 0000 is situated behind an open gate on the back wall. Once a player opens Door 0000, all players (whether dead or alive) will be teleported to The Reception after a skippable 15-second intermission. An empty doorway will appear behind them presenting signs of Curious Light, this empty doorway also appears when a player enters or exits The Rooms. 
===Secondary Locations===
====Multi Gate Room====
The Multi Gate Room is a room with many gates, which spawns frequently throughout a run. The room consists of up to eight gates, with a door behind each of them. Only one of these doors will allow progression to the next room. This room may spawn as a dark room, and Timer Levers may spawn in this room. 
==== The Wall Room====
The Wall Room is a room that players are likely to encounter during a run. It is a large room blocked by a low wall. Players will have to crouch for an extended period of time underneath the wall, which contains many scattered boxes. This room may spawn as a dark room, and Timer Levers may spawn in this room.
====The Maintenance Hallway====
The Maintenance Hallway is a room that players are likely to encounter during a run. It consists of 4–12 doors, with only one door leading to the next room. There will be yellow and black tape at each doorway, and pipes at both ends of the room. This room may spawn as a dark room, and Timer Levers may spawn in this room. 
==== The Staircase Room ====
The Staircase Room is a room that players are likely to encounter during a run. This room consists of up to 10 sets of stairs, running upwards and downwards. Each stairway will lead to a floor that contains a door. Only one floor will contain the proceeding door. This room may spawn as a dark room. Timer Levers cannot spawn in this room, although they may generate within side rooms. 
== Bugs== 
*Players may be able to hide in drawers to avoid Blitz (this is not consistent) unless the drawer has a coin.
*There is a rare bug that can cause a fake door to have 2 handles.https://doors-game.fandom.com/wiki/File:Capture_d'écran_2024-03-22_210528.png?_rcid=51120 This can also happen in the Hotel and The Mines.
*Sometimes, even when Blitz is not rebounding, it will still show the rebound animation and sound.
*There is a bug where the the Lookman can spawn slightly lowered in the ground.https://doors-game.fandom.com/wiki/File:Lookman_in_the_ground.png
*If a player has a weak internet connection or is playing on low graphics, Blitz's glow may remain in rooms until lighting updates.
*If a player does not have the Detour achievement and glitches through the barrier blocked by Curious Light and clip some invisible walls, a private error message will pop up saying "You need to unlock "Detour" to access elevators in the Backdoor!".
*Blitz can leave a lamp lit even after breaking it, although the glitched lamp will not emit any light.
*There is a bug where when entering a room with unnumbered doors somehow fails to generate the door to the next room, instead its replaced by a regular unnumbered door or a giant black box and making it impossible to progress and also making Haste guaranteed to end a run.
*On low graphics settings one can semi-accurately spot whether or not a door is an instance of vacuum or not due to light pouring out from under the door and nearby walls. Though, this only works when the room behind the door has lights, and so is not fully accurate when searching for splinter rooms.
* If you go forward just as you opened a locked door, sometimes you can go up through the ceiling and end up outside the room. You can't die or leave from this area, guaranteeing Haste to end the run. 
**However, in some cases, you won't go through the ceiling and you'll be stuck in mid-air. In this case, and if in the room where there is one or more closets, you have to walk backwards to the closet and hide into it. After exiting the closet, you are back to the floor and you can progress again.
==Trivia== 
*The Backdoor is the second sub-floor to be added to DOORS, with the first being The Rooms.
*Before the post-Hunt update, the Backdoor was in the Lobby, did not require the "Detour" achievement, and had an elevator. 
**There was a sign in the Hunt lobby which notified players that once the event was over, the Backdoor would become more difficult, although no major changes seem to have been made.
*Redibles confirmed that the Backdoor is fully planned, developed, and released in 2 weeks and most of the idea used in the Backdoor are recycled scrapped ideas."fully planned, developed, and released in two weeks... -Redibles, X
*The Backdoor is canonical to the DOORS' Lore."..the floor itself is canon!" -LightningSplash, X
*The exit door in -01 is an unlabeled -00 door. This can only be seen using exploits or by looking through the game files.
*The achievement description for "Other Way Around", reading "Yeah, I've got time." is a reference to The Incredibles, to the Bob Parr's line.
*The Backdoor is currently the fastest floor to clear, including RETRO Mode. (April Fools 2024 Event) The average time to clear the Backdoor is around 7 minutes and 40 seconds, whereas the average time to beat RETRO Mode is between 9 1/2 minutes to 10 1/2 minutes. Ten minutes is impossible as the Drakobloxxers arrive in 600 seconds, which is 10 minutes.
*If the timer has over 2 minutes, the main ambience will not play, due to the fact it is a soundtrack last for almost only 2 minutes.
* Time remaining on the timer affects some odds:
**If there is less than 1 minute left, Blitz will rebound less.
**If there is less than 30 seconds left, Blitz will never rebound, so players can keep going and find a lever faster. This is also the same when there is literally NO time left.
**Levers also are affected if there is less time left. 
***If more than 2 minutes remain, no levers will spawn, because players have enough time.
***If a lever that spawns when there are more than ~65s left, it will add 30 seconds.
*** Otherwise, if there are less than ~65s left upon spawning, it will add 60 seconds. However, if the timer goes below 65 seconds when the time lever spawned before it was 65 seconds, it can still have 30 seconds.
*Only one Timer Lever may be loaded at a time. The next Timer Lever may generate as soon as the previous one unloads given it meets the time constraint for it to spawn.
**Since Glitch unloads 4 rooms behind player, and the game always generates 1 room ahead, Timer Levers will spawn at MINIMUM 5 rooms apart from each other (excluding the guaranteed spawns at Doors -50 and -01). Therefore, if you flipped a Lever in the current room or in the previous 3 rooms, there is no need to scour the side rooms for more levers.
**As of the Content Update, this is no longer the case. Timer levers will now spawn more frequently, possibly every room, until one lever is flipped, at which point generation goes back to every 5 rooms.
*The ambient sounds will play when the timer hits a multiple of 15, excluding the "tension" audio that plays on the last 30 seconds. 
**This will only happen if there are less than 2 minutes left, as the audio only starts at that time.
*The Backdoor might get a touch up in the future.Q: "Will you expand the backdoor to a full floor with 100 doors?" A: "Nah, we might touch up the backdoor just a bit though" - Lsplash, Twitter
*Like The Rooms, players are not able to use revives in The Backdoor. 
**Prior to The Mines update though, players could still revive as long as the timer is above 00:15.
*The Backdoor will not receive any modifiers directly. However, mechanics from The Backdoor will be coming as modifiers (See Upcoming Content).
*If a player escapes The Backdoor, they will be granted 50 knobs.
*It is almost guaranteed to get all room types in a single run.
*Similarly to The Rooms, when exiting The Backdoor, the game counts it as a floor, with a parenthesized "1" next to it. (As of now, The Rooms no longer has a parenthesized "2", because it was changed to "1", so that people won't get confused about The Mines and The Rooms.)
*Similar to The Rooms, Hide is not present in The Backdoor, so players can hide for as long as they wish (until Haste spawns).
*When exiting The Backdoor, it plays the same animation as when exiting The Rooms.
*Miscellaneous entities don't spawn in The Backdoor, such as Jack, Timothy, and Shadow (excluding Glitch).
*When Haste spawns, it will print "erm.. hello bro" into the console.
*Judging by the Backdoor's design and location, the floor is most likely the Basement floor of the Hotel. This is proven by stairs that lead down to an area with Backdoor decorations, including a blocked door with a broken timer, in the Lobby.
*A quote from Curious Light states that The Backdoor is a very old place, however, not any older than The Hotel, despite being in much worse shape and almost forgotten, and some things missing within it.https://youtu.be/Uq2yRbbCR0I?si=1rpZnB04j9k0h1FG&start=65
*With admin panel enabled, if you stall/run away from Haste for too long, it will kill you instantly with no jumpscare, and bypassing god mode and crucifixes.
*The Blitz, Oh modifier is most likely a reference to the character Blitzo from Helluva Boss.
