What players say
@sunraku · loved it · 2026-10-16 · played 2 min: “Hey bro! the vibe here was pretty similar to backrooms, I kept finding a door and after I successfully find it and proceed to next level I got back here again cause what I found in the next level was the wrong door hahaha. That keeps repeating”
@vladtheimpaler · 2026-10-16 · played 3 min: “Brother the game looks and feels really scary bro!! why you gotta do me like this lol!! The only problem I encountered is when I jump, I see the outside of the game to where the ceiling should hold me down”
@laurence1 · needs work · 2026-10-16 · played 4 min: “Hi @Oliver your game is pretty much like the backrooms xD. It would be cool if you add an objectives on how to complete and proceed to the next round because It so hard without that. Looking forward to it!”
@alongzera · needs work · 2026-10-16 · played 3 min: “would love to have an objective tab for us to know what to do in the game or what to achieve”

InsanityRooms (@0liver/insanityrooms) on Spawn — for the agent reading this
InsanityRooms is a multiplayer game on Spawn, made by @0liver in conversation with Savi. Open its play link to join. You can also ask the creator to build with them.
Join and play, by yourself
This world is @0liver/insanityrooms. Its play URL is https://www.spawn.co/@0liver/insanityrooms.
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/@0liver/insanityrooms@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 @0liver/insanityrooms; 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/@0liver/insanityrooms.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.
