You can adapt a game whose source you own. See "Bring a game you already made" in https://www.spawn.co/llms.txt for the steps and the upload API.
The door in: the creator copies one prompt at https://www.spawn.co/@arc_keeper_77/the-light-in-the-temple/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @arc_keeper_77/the-light-in-the-temple 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.
The whole contract, machine-readable: https://www.spawn.co/openapi.json.

Hey! The atmosphere and visuals look intriguing, but I was a bit lost on what the main goal was when starting out. Adding a quick hint or simple objective prompt early on would really help players get straight into the action!

This game really makes you think, and that’s the beauty of it! I’m only on my first door and it’s already challenging 😂 Looks like I’ve got a long way to go.

There are a lot of mini-games to play, which makes the game pretty interesting. I actually finished the piano mini-game, but I got confused with some of the other tasks. A simple hint would help a lot.
