Solo dev @apekshik released a web-based, infinitely evolving Backrooms game where Claude Opus 5.5 keeps generating new rooms, with a correction loop that lets the AI fix broken rooms automatically. In under 36 hours it drew 35,000 players and 9,600 hours of play, with 1,200 concurrent players using proximity chat. The server chunks shared space into 200-player worlds, and a shared-space server sustaining 2,000 players in a single world is launching soon.
