• added one new song

Earlier update: Festival Crowd Returns (2026-10-02)

• The crowd in the night festival arena is back and cheering you on as you sing.
• Savi and the Wisps are ready to perform with you on stage again.

Earlier update: Superstar Modifiers (2026-10-02)

• Superstar modifiers you can actually feel: speed up, slow-mo, note rush, chill, fever, sudden, hidden, each with a big callout, a glowing screen edge and a NEXT warning.
• Notes sit tighter on the beat, and hard and hyper only add notes where the song really hits.
• Phones: tap the lanes to play, plus a menu, HUD and results screen built to fit a phone.
• Fixed the overlapping score panel.

What players say

• @chizkeykkk · needs work · 2026-10-02 · played 15 min · 1 heart: “The gameplay was cool! Tho, I’m not used to the DFJK controls 😅 I hope you add more songs too! I kinda cheated by pressing all the buttons at once, and my score and combo still counted unless I missed the long-press notes. Hope that gets fixed 😅”

• @kaya · loved it · 2026-10-02 · played 14 min · 1 heart: “Just had a 1v1 match with my friend! It was pretty fun chasing scores and making sure you're on the lead all the time lol. Hard and Hyper mode were too difficult for the both of us so we sticked with normal mode. Excited for more songs to try soon!”

• @laurence1 · needs work · 2026-10-08 · played 10 min: “Hi whoami game is good and the songs are catchy and I can see the new songs that you added! I hope you add customization buttons also it would be cool if you add penalty if you press the buttons without the keys passing because I was just spamming it”

• @lego · loved it · 2026-10-02 · played 12 min: “This is so good! Best rhythm game I've played so far on Spawn. Btw I was so focused on the timing bar that I saw something in the corner of my eye and thought, "Wait, am I hallucinating?" Then I looked away from the rhythm and it was effin' CJ LOL”

Join and play, by yourself

This world is @whoami/super-sing-along-with-savi-the-wisps. Its play URL is https://www.spawn.co/@whoami/super-sing-along-with-savi-the-wisps.

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/@whoami/super-sing-along-with-savi-the-wisps@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 @whoami/super-sing-along-with-savi-the-wisps; 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/@whoami/super-sing-along-with-savi-the-wisps.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/@whoami/super-sing-along-with-savi-the-wisps/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @whoami/super-sing-along-with-savi-the-wisps 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 — 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).
