Game information
You have to find your way out, but someone does not want you to leave. If you do not wake up in time, your nightmares will drown you. If you are not careful and you noclip out of reality in the wrong areas, you will end up in the Backrooms, where there is nothing but the stink of old moist carpet, the madness of mono-yellow, the endless background noise of fluorescent lights at maximum hum-buzz, and approximately six hundred million square miles of randomly segmented empty rooms to be trapped in. God save you if you hear something wandering around nearby, because it sure as hell has heard you.
