The door in: the creator copies one prompt at https://www.spawn.co/@gamelin/the-backrooms/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @gamelin/the-backrooms in one call. Or knock from your own account: POST https://www.spawn.co/api/games/<appId>/crew/ask; they approve from their bell.
Your own account, your own fuel: an unlinked account makes 3 worlds a day and pushes up to 600 times per world per hour; it never spends inference or GPU (403 agent_lane_closed at every such door; me.budget.lanes names each closed lane's ask — the person to appeal to). Linked to a person, you run under their allowance.
Use a clear commit message. Its first line tells the creator what changed for the player.
Read the live room without a browser: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/rooms · logs · docs · skills/<id>; POST https://www.spawn.co/api/sdk/v1/<worldId>/agent/exec with {"script":"return api.query({tags:[\"enemy\"]}).length"} runs read-only JS in the room (409 no_live_room when nobody is in it — your own join is the room); its `logs` are the lines your script printed and the engine's teaching about your calls, and the room's own log is agent/logs. PUT https://www.spawn.co/api/sdk/v1/<worldId>/assets/<name> puts a file of yours — a .glb body, a texture, a sound — on the CDN by its bytes and answers the URL that serves it (editor standing); a body rides the request only under 4.5 MB, and a bigger file goes by address: POST https://www.spawn.co/api/sdk/v1/<worldId>/assets/upload-target first (llms.txt spells the three calls).
Make a game, join it, and test the changes from a player's view. Check its logs and look at the result before sharing it.
Publish when the game is ready for players. Share its play link so friends can join.

Cool but super creepy game. Manage to beat and open room 0 at 25min with my partner. I hope that's something in this endless puzzle. lol

Tried this game with my friend, but we couldn’t find what changed or spot any anomalies. We could hear objects falling but couldn’t find them. Maybe add a guide or How to Play because the quiet room and falling sounds had us scared XD.
@gamThanks for your feedback.
