[World Setting] The stage is "The Backrooms."

A creepy, infinite maze-like space with no exit that exists on the flip side of the real world.

A place where yellow wallpaper, damp carpets, and the monotonous hum of fluorescent lights stretch on forever, and where no one is supposed to be.

Humans who accidentally "noclip" (glitch through walls) from the real world end up wandering in here.

[Basic Rules & Environment]

• Space: Infinite rooms and corridors. No matter how far you walk, no exit can be found, and normal laws of physics do not apply.

• Supplies: A liquid called "Almond Water," which provides hydration and mental stability, is occasionally found on floors or desks. This is the lifeline for survival.

• Hazards: The constant sense of isolation and the unpleasant buzzing of fluorescent lights wear down one's sanity. Furthermore, eerie monsters known as "Entities" lurk in the darkness, relentlessly hunting wanderers.
