What players say

• @chizkeykkk · 2026-09-21 · played 28 min · 1 heart: “I like the idea of the game, and I think it could be really fun with friends! I tried playing with a bot on Very Hard with all the chaos activated, but it actually made me win easier because the bot couldn’t even reach the center where the Crown is lol 😂”

• @lego · 2026-09-19 · played 18 min · 1 heart: “I can already see this being real fun with friends! I tried Chaos on Very Hard against the Wayfinder bots, and they're having a hard time getting into the center lol”

• @kaya · 2026-09-17 · played 33 min · 1 heart: “Team vs Bots + Very Hard = fun. it was challenging to dodge them and my teammate was pretty good with passing lol. would be nice if there were other gamemodes/maps that offer some gameplay variation.”

  • @djdef1le (maker) replied 2026-09-17: “In section 03 of the Menu there are different Hazards you can choose for the Map , I really like “Spin Cycle” but you can choose “Chaos” and decide which Hazards you want at the same time - as few or as many , also there is a Night Mode that the Arena can be changed to !!”
  • @kaya replied 2026-09-19: “chaos was definitely... chaotic LMAO. fog + avalanche is a deadly combo so i had to take that out hahahaha. aside from spin cycle, i also liked explosives, but i think the radius indicator was a bit hard to see since it was very light”
  • @kaya replied 2026-09-19: “radius indicator for the bombs on the ground*”

• @yujiro · 2026-09-17 · played under a minute · 1 heart: “Gorgeous graphics combined with the tense challenge of dodging enemies to keep your crown! Having to play smart defensively while controlling the board makes every match intensely satisfying.”

  • @djdef1le (maker) replied 2026-09-17: “Thank You Kindly!!”

• @vladtheimpaler · 2026-10-09 · played 14 min: “Brother, your game is amazing! I love the concept, especially the fun of stealing the crown and juking other players. It would be awesome to see more maps in the future, maybe with a lobby where players can vote on which map to play.”

  • @djdef1le (maker) replied 2026-10-09: “Ayyy Thank You Kindly , I was contemplating having a Variation of it that hangs Upside down , and some how it keeps you standing on the top / central part of it , but a different way to look at it , and another Idea I had for a Map was an Anti-Gravity but still controlled area where people are able to Juke other players while in a changing environment”

Join and play, by yourself

This world is @djdef1le/crownfault. Its play URL is https://www.spawn.co/@djdef1le/crownfault.

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/@djdef1le/crownfault@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 @djdef1le/crownfault; 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/@djdef1le/crownfault.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/@djdef1le/crownfault/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @djdef1le/crownfault 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.
