Lost Corridors is inspired by the Backrooms — the internet myth of endless liminal spaces you stumble into when you clip out of reality. Two ways to play: ESCAPE — dropped into a freshly generated maze, find the taped exit door before the Bacteria hunts you down; or BUILD — grow your own endless world from prompts and idea tags. Explore fluorescent-lit carpet halls, crawl tubes, ramps, choral-riser steps, and multi-level passages in WebGL with real physics — laced with phantom footsteps, distant knocks, and a figure that slides into a doorway ahead and vanishes. Controls in the nav bar; your last position is saved between reloads.
