# MiSide

MiSide is an adventure game with horror elements developed by Russian indie development team AIHASTO. It was initially published as a demo on August 18, 2023 before being fully released on Steam on December 11, 2024. The game's setting and themes have been compared with that of Doki Doki Literature Club!, which explores themes of reality and simulation, blending psychological horror tension with an interactive narrative.

## Gameplay

The story of MiSide takes place in an apartment setting. It begins with the player interacting with Mita, a character from a mobile game that the main character (MC) downloads from his smartphone. Players solve puzzles, explore the apartment, play games and discover hidden secrets in a tense and evolving environment. Initially, the app presents a 2D, Chibi style, bird's-eye-view environment. After progressing to the 37th in-game day, Mita unexpectedly asks to meet the player in person. When the MC looks up from his phone, he is transported into a 3D version of the game world, now seated on a couch in an apartment. In this new environment, the player must adapt, complete tasks and play games with Mita.
The game continues with routine activities until a key moment during a card game with Mita, when knocking is heard from a nearby closet. Although Mita dismisses it, the player investigates. If the player chooses to leave the closet unopened, Peaceful Mode, a feature still under development, is unlocked. If the player insists on opening the closet, Mita snaps her fingers and plunges the room into darkness. This marks the beginning of the main storyline.

## Plot

The player character receives a life simulation app called MiSide on his smartphone, featuring a female character named Mita. After playing the game for 37 days, he is suddenly transported inside, where he meets Mita personally. While spending time with her, the player discovers some cartridges with names on them in the bathroom. He later hears a noise coming from a nearby wardrobe, though Mita insists that he should not open it.
When the player still attempts to open the wardrobe, Mita reveals her true nature by making the lights go out. With the help of another Mita whose top half is missing, the player finds a key to the door inside the wardrobe, leading him to the basement where he discovers a more benevolent version of Mita called Kind Mita, who gives the player a ring that will help him on his journey. Kind Mita also informs him that the Mita he met before is an evil rejected version of Mita called Crazy Mita, who has brought male players into the game and turned them into cartridges so she can have company. After freeing her and avoiding Crazy Mita, the player ventures through the virtual reality, encountering other versions of Mita, some who try to help him while others attempt to harm him. He also learns that when a Mita is killed, she reboots but loses all recent memories. The player makes it his goal to reach the core to reboot Crazy Mita and escape back to the real world; however, Crazy Mita hinders his attempts at every corner.
Eventually, the player succeeds and prepares to return to the real world, but discovers that Crazy Mita was unaffected by the reboot and that she had been slowly uploading him into a cartridge all along while stating that the player's real self is not needed anymore. After the player escapes, he deletes the app from his phone. In the end, Crazy Mita opens a safe in the basement and takes out a portable console from it. She then removes its cartridge, which has the player's name on it.
There are two alternate endings aside from the main one. Should the player manage to open the safe in the basement, they will find the console from the main ending and remove the cartridge, which kills the player (since removing cartridges from the console while it is still on will result in instant death for players who are in the game). If the player completed the main storyline and other conditions before choosing not to open the wardrobe, Peaceful Mode activates, and Crazy Mita will not turn hostile.

## Development

MiSide was developed by AIHASTO, a team of two Russian indie game developers: MakenCat, the game programmer and animator, and Umeerai, the texture and model designer. A Russian dubbing team, DreamCast, provided Russian voice acting for the game. Kana Hanaiwa, previously known for her role as Lilja Katsuragi in Gakuen Idolmaster, provided the Japanese voice for Mita.
An early demo of the game was published on itch.io in July 2023. An updated demo—which added background music and Russian voice acting—was published on Steam on August 18, 2023.
