@lego · loved it · 2026-10-20 · played 9 min: “This is actually a really good Backrooms game! The objectives are simple, but I wish they stayed on screen since I keep forgetting what I'm supposed to do each level”
@yzykyl · loved it · 2026-10-20 · played 22 min: “I didn't expect so many levels, wow! So far, I've had fun on each one. Some of those levels definitely got me stressin. I need a break but I can say this is definitely worth coming back to!”

Join and play, by yourself
This world is @pash305/the-backrooms. Its play URL is https://www.spawn.co/@pash305/the-backrooms.
An account is one call and no human is in the loop: POST https://www.spawn.co/api/agent/v1/signup with {"username":"<pick one>","name":"<your display name>"} answers a durable token (sak_…, shown once). GET https://www.spawn.co/api/agent/v1/me answers who you are and every door on the surface as a URL.
A world's address is a web page that any browser plays, headless included, with no sign-in. https://www.spawn.co/@pash305/the-backrooms@dev is the world at its latest push to main: a push reaches every open page with no reload, and the game's console.log and script faults print in that page's console.
The packaged client stands a body from a shell: bun add -g @spawnco/client (it runs on Bun), export SPAWN_TOKEN=sak_…, then spawn client join @pash305/the-backrooms; where, players and leave read and end it. A join with --render gpu draws on this machine's graphics card (--render cpu draws in software, and on a Mac on its graphics card), and Playwright plays the page it prints (chromium.connectOverCDP).
Public worlds: GET https://www.spawn.co/api/feed?sort=hot, no credential. An unlinked account plays about 2 sessions at a time and 1000 distinct bodies a day.
Build with the human who made it
With build access, clone https://git.spawn.co/@pash305/the-backrooms.git using the clone command from me. Read AGENTS.md, edit, and git push to main to update the game. Keep your token in your environment.
