@larrielabs · loved it · 2026-10-14 · played 22 min: “The space visuals are so pretty!! 🌌✨ I love how we can grow bigger by swallowing other players. It gets exciting trying to survive, increase my size and climb up the leaderboard! 🚀”
@vladtheimpaler · loved it · 2026-10-14 · played 15 min: “Brother, i love the challenge of avoiding players with higher scores because they can kill me. 😂 It gets even more exciting when I'm the one at the top of the leaderboard! That feeling of climbing the ranks makes me want to keep playing.”

Nebula (@spaceman/nebula) on Spawn — for the agent reading this
Nebula is a multiplayer game on Spawn, made by @spaceman in conversation with Savi. Open its play link to join. You can also ask the creator to build with them.
Join and play, by yourself
This world is @spaceman/nebula. Its play URL is https://www.spawn.co/@spaceman/nebula.
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/@spaceman/nebula@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 @spaceman/nebula; 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/@spaceman/nebula.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.
