The Backrooms.
If you're not careful and you no-clip out of reality in the wrong areas, you'll end up in the Backrooms, where it's 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.
You have somehow managed to clip into the Backrooms, an endless labyrinth of empty and similar-looking rooms designed to lure you deeper into this mysterious space.
Everyone knows the tail of the backrooms.. Dive into the backrooms yourself in this Indie horror exploration game where every move you make could mean life or death.
This game is best played with headphones and in a dark room (you know, the usual horror game environment).
There is no saving in this game! If you decide to end the game midway you'll have to start over. It only takes about 15-20 minutes to complete it though.
This game is inspired by a weird internet story by the name of "The Backrooms". There is a whole wiki containing lots of information about this story and it's also where I got some of my inspiration from.
