What players say

• @makeriffic · 2026-09-10 · played 7 min · 1 heart: “I have played a song and only got 1 star with 167500 final score and 73.1% accuracy lol. It was fairly difficult especially for first timers, It was really hard with the JKL buttons, it was new to me. Nice game! I was vibing while struggling to press right at the same time lol.”

  • @badgerblunts (maker) replied 2026-09-10: “i dont think t will even place but it is a fun. the JKL took me some getting used to but once you get used to it its relly fun.”

• @sunraku · 2026-09-20 · played 57 min: “Hi bro! I am still trying to hit the right notes on practice. I was just uncomfortable on the back instrument or what ever you call that. It is because the game platform (which was the notes were popping out was a bit out or not aligned to it (the back instrument like guitar) . Is it possible to improve it? I was trying not to see that back part but its my eyes were keep looking at them and then I noticed I missed to hit a key.”

• @lego · 2026-09-18 · played 10 min: “Man, I suck at rhythm games lol, even on Flow intensity. But honestly, I think this is a pretty fun way to exercise my brain and fingers.”

  • @badgerblunts (maker) replied 2026-09-18: “i do need to fine tune it. im going to work on it this weekend”

• @sunraku · 2026-09-13 · played 57 min: “Played this and I like the music and it is fun to play. However, after several taps... Oh I'm suck at this hahaha. Anyways I will try to do it more times. Practice makes perfect.”

• @fc_zer0x1 · 2026-09-11 · played 11 min: “love it. Song of storms and Gerudo Valley are great 😎 Quite fun and with some polish could be amazing. Problem is ofc nintendo would sue the s* out of you for this 😂 also for some reason the game makes my browser freeze after some time. Ram and CPU usage don't increase so not sure what is.”

  • @badgerblunts (maker) replied 2026-09-11: “im glad that you liked it and can easily change how everything looks but when you get an idea and you get stuck in the flow you just have to go with it. There is a good skeleton for something cool here, also i could not let 0liver be on they own. Plus the worst i might get is a S&D, not that that will happen because i can change everything at the snap of a finger. They are beefing with Rockstart rn anyhow and going to be swimming in money from Ocarina of times new launch anyhow.”

Join and play, by yourself

This world is @badgerblunts/signal-break. Its play URL is https://www.spawn.co/@badgerblunts/signal-break.

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/@badgerblunts/signal-break@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 @badgerblunts/signal-break; 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/@badgerblunts/signal-break.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.

The game's API reference reads by section: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/docs?section=<heading> (no section named: the reference's opening and every heading; ?section=guide: AGENTS.md whole).

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/@badgerblunts/signal-break/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @badgerblunts/signal-break 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 3000 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; 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; an open page or a client body is a player in a room), and its `logs` are the lines your script printed. PUT https://www.spawn.co/api/sdk/v1/<worldId>/assets/<name> puts a file of yours — a .glb body, a texture, a sound, a video (.mp4) — 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 through POST https://www.spawn.co/api/sdk/v1/<worldId>/assets/upload-target (https://www.spawn.co/llms.txt spells the three calls).

Build, test, and share

Publish when the game is ready for players. Share its play link so friends can join.
