Acatalepsy (アカタリプシー, Akataripushi) is an early 2012 fangame by Arakawa, depicting the dark subconscious of Naoto, a hikikomori with only his moody dreams and a Famicom-like system to accompany him.

The game's read-me file warns squeamish viewers of "shocking" and "grotesque" content and color schemes. Much of the music used is disorienting and eerie, and chiptunes are used often.


When you sleep in the bed, you will enter Naoto's "dream room." Little has changed other than the world outside, and you can not interact with the bed or laptop. If you interact with the game system, the top will open to reveal a missing game cartridge. Naoto will now be able to exit the room.

There are five portals in the nexus, six if you count Naoto's door. One portal, a blue door, leads to an empty room that will initiate the ending later on, after all effects are collected and placed in this room. (Effects become TVs and can be picked up again if you are not ready to view the ending.

...waking up after dropping all effects and interacting with Naoto's TV shows the view of Naoto's room from a TV screen, and all of his furniture being deleted at once, then his door and carpet,his room, and finally Naoto is gone, and his game system being the only thing remaining during the ending credits. ...Possibly means that Naoto is just a character in a video game, and realizes this, or is trapped in the TV.
