Pearl Spire

Newest update: The Sky Islands (2026-10-26)

• Floating sky islands now rise over the sea. Hop the Lookout Steps and Pier Steps, ride the updraft pads, and find a lantern, shrine, bench or ball on every island.
• Wind-Chime Isle marks the one gap you have to fly, with lanterns above it and buoys below, out to Stilts Heights and its shrine.
• A little train runs between Airfield Halt, Landing Halt and Heights Halt. Press E on the platform to board.
• The airfield has grown: a control tower with a red beacon, a waiting hut with a timetable, the hangar, a windsock and lights along the strip.

Earlier update: X-card hint fix (2026-10-25)

• Your spirit can grow nine light-woven tails that sway and trail as you move
• Sparkles drift around the spirit, and legs and shoulders join the body cleanly
• The bear, bunny and pig bend cleaner when they run, jump and sit
• Smoother arrival and camera, fewer hitches
• The start hint no longer hides under the rope button on small screens.

Earlier update: Kinder Ways Down (2026-10-24)

• Stepping or jumping off a draft well ledge now floats you down to the well floor by the door.
• R takes you to the door of whatever room you're in, and a soft hint shows it when you look stuck.
• The dragon carries you anywhere along its back while it flies.
• Fold the parasol to dive, hold SPACE to snap it open and brake into a glide.
• Long glides curve back toward the island on the sea wind.

What players say

• @sunraku · loved it · 2026-10-25 · played 8 min: “Hey bro! The first climb was difficult haha. There's this part of the tower that when I take my foot there, I just fly + the fly was hard to control feels like it has a big radius when I am doing a U turn.”

  • @levai (maker) replied 2026-10-26: “Haha thanks for sticking with it! You're right, the first climb is too tough for a first climb. I'm adding a checkpoint partway up and making the crumbling steps easier to spot. The gyro's getting a proper way down and tighter turns too. Let me know where on the tower it launched you, I want to track that spot down.”

• @yzykyl · loved it · 2026-10-24 · played 18 min: “Got frustrated at the first tower because I couldn't climb it well so I decided to explore around on the helicopter. Got to the ice caves and I still got frustrated cos I kept on falling LOL. I find it pretty cool having so many places to explore tho”

  • @levai (maker) replied 2026-10-26: “Love that you went exploring when the tower got annoying, that's kind of the point haha. The first climb's getting a checkpoint halfway up so one slip doesn't cost you the whole thing. Ice caves are on my list too. Thanks for playing so long!”

• @makeriffic · loved it · 2026-10-24 · played 16 min: “I love how challenging the tower was! Every space matters and I think that's what is the challenge going up in this tower. I just find the controls for the helicopter to be very add. It is inverted and doesn't have a down controls. It just go down.”

  • @levai (maker) replied 2026-10-26: “Thank you! Glad the "every step matters" feeling came through. The inverted controls are fixed now, and a real descend button is coming so you're not just sinking anymore. Really appreciate you spelling it all out.”

• @jeon · loved it · 2026-10-24 · played 7 min: “Damn, this game is really nice! 🔥 So much to do! The helicopter is hard to control, and I kept falling in Frozen Cathedral because of the jumps haha 😂 Still love it! 💯”

  • @levai (maker) replied 2026-10-26: “Thank you, that means a lot! The gyro's getting easier to fly with a real way down and tighter turns, and I'm taking another look at those Frozen Cathedral jumps. Glad you still had fun falling haha.”

• @flickaboo · loved it · 2026-10-24 · played 17 min: “The tower climb is an interesting concept! I fell while trying to make my way up, so I gave it another go. The challenge is there, but I won't be returning for another climb. 🐍”

  • @levai (maker) replied 2026-10-26: “Totally fair, and thanks for giving it another try. That first stretch was way too unforgiving. I'm adding a checkpoint partway up and making the hard parts easier to read. If you ever come back, it should feel a lot better.”

Join and play, by yourself

This world is @levai/pearl-spire. Its play URL is https://www.spawn.co/@levai/pearl-spire.

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/@levai/pearl-spire@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 @levai/pearl-spire; 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/@levai/pearl-spire.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/@levai/pearl-spire/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @levai/pearl-spire 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).
