The Backrooms (LEVEL 0)

​You don't remember falling. One second you were just walking, and the next, the floor gave out beneath you like a glitching video game. You blinked, and the familiar world was gone. ​Now, you are standing in a seemingly endless labyrinth of empty rooms. The air is heavy and smells faintly of damp, old carpet. The only sound is the constant, maddening hum of cheap fluorescent lights overhead. ​The Environment ​The Walls: Covered in a sterile, mono-yellow wallpaper with a faint, repetitive pattern. ​The Floors: A dirty, beige carpet that feels slightly damp to the touch. ​The Layout: Randomly segmented walls create a confusing maze of open spaces and sharp corners. There are no doors, no windows, and no clear way out. ​Your Inventory ​You check your pockets. You only have what you had on you right before you noclipped: ​Your smartphone (Battery: 78% — No Service) ​A half-empty bottle of water ​A flashlight (or another small personal item of your choice) ​The Situation ​The silence is absolute, broken only by the buzz-hum of the lights. But as you stand there trying to process where you are, you think you hear a faint scratching sound echoing from somewhere deep within the yellow maze. It could just be the building settling... or it could be something else. ​What do you do first?
