SUBLEVEL 0 — Backrooms Survival

A first-person, landscape-mode Backrooms survival horror. Every floor is procedurally generated: mono-yellow wallpaper, damp mustard carpet and hundreds of flickering fluorescent tubes — with only a pool of nine real lights and zero image or sound files (every texture and sound is generated at runtime). Nerve drains as you wander; almond water restores it; an entity that only tracks your last known position hears your footsteps before it sees you. Follow the signal meter to the stairwell and climb out — into a bigger, darker floor.
