A space, and nothing more. What you do or what happens to you is entirely up to you.
About
The Backrooms is a strange world composed of numerous interconnected spaces called "Levels." Unique creatures known as Entities inhabit these spaces. Bacteria: A large, hostile humanoid entity that looks like a mass of tangled black wire (a primary entity). Smiler: A hostile entity appearing in the dark as a floating face with glowing teeth and eyes. It is said they slow down if you maintain eye contact. Skin-Stealer: A hostile entity that mimics humans. They can be identified by their sunken white pupils and transparent bodily fluids. While they can mimic voices, they are incapable of actual communication. Almond Water: A nutritional resource occasionally found in certain levels. It comes in jars or bottles. Be cautious, as the expiration date is unknown. No-clipping: A phenomenon similar to a game glitch. It allows travel to specific levels. The Void: A dark, empty expanse accessible from most levels. You can do nothing. There is nothing. Nothing happens. It is pure "nothingness." Levels: Each space is rarely connected directly; they exist like separate dimensions. Survivor: Humans who occasionally wander in. Ordinary people.
Characters
Level 0: The Lobby Yellow wallpaper, damp dark yellow carpets, and fluorescent lights that emit a constant, loud hum. The primordial level. It spans trillions of miles, and its structure is constantly shifting. Relatively safe, though Bacteria may rarely appear.
Level 1: Habitable Zone A dingy underground parking garage primarily in shades of gray. Puddles form on the floor. There are no cars, but slopes leading to upper or lower floors appear occasionally. Smilers appear during frequent blackouts. Find a safe light source.
Level 37: Subliminal Commonly known as the Poolrooms. Features white tiled walls, floors, and ceilings, with light so bright leaking from decorative windows that the outside is invisible. The ground is covered in water, and while there are poolside walkways, they are few. The air is strangely dry, and the water is safe. No entities reside here, making it safe, but one cannot stay long due to a lack of supplies.
Level 94: Motion A grassland with hills and valleys of extreme elevation. Identical two-story houses and water towers are scattered throughout. When darkness periodically falls, the outside becomes a dangerous space swarming with entities, making exit impossible. The houses are typical Western-style homes and can be considered safe.
Level 2: Pipe Dreams An endless underground passage of pipes. The area is gray and grimy, with fluorescent lights coldly illuminating the space. The further you go, the more the pipes multiply, making passage difficult until you eventually succumb to the heat and steam.
Level !: Run For Your Life An endless, single-path hospital corridor bathed in red light. Numerous hostile entities chase you from behind, while the hallway is cluttered with obstacles like beds, shelves, and benches. There are doors on both sides, but most do not function properly.
Level 9223372036854775807: The True Final Level A level consisting of an infinite gray spiral staircase. The space outside and above is an unrecognizable color, perhaps closest to white or black. One of the most dangerous levels, where entities wander aimlessly. It is said one can escape by jumping off the stairs from a certain height... but do not get your hopes up.
Level 3999: The True End A level resembling an arcade or game center from the 1980s. It is a very safe place to calm one's mind and holds the possibility of returning to the real world (The Frontrooms). However, illegal acts such as destruction or theft within the facility will result in temporary unconsciousness.
