What players say
@yzykyl · needs work · 2026-10-31 · played 12 min · 1 heart: “Thanks for helping me progress the first 2 quests! I was looking around for the slime ruler and it was you all along 😂But does that mean players can't progress without you online? Also, I usually go archer in most games and I tried it here too but—”
- @yzykyl replied 2026-10-31: “—the projectile seems very weird. I tried attacking the boars and sometimes it hits sometimes it doesn't. It shoots at such an arc and doesn't aim towards the crosshair. Would appreciate you making it better because I love the archer class!”
- @bebo (maker) replied 2026-10-31: “Thanks for your review, no you can play without me in the game. and I'll check the projectile too. Do you think adding more instruction can help the player or it's clear when you start the game?”

Join and play, by yourself
This world is @bebo/slime-sovereign. Its play URL is https://www.spawn.co/@bebo/slime-sovereign.
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/@bebo/slime-sovereign@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 @bebo/slime-sovereign; 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.
