Released 2026-09-24. 5 updates since release, the newest 2026-10-14.
Newest update: Lost Sheep Drifts By (2026-10-14)
- A lost sheep now drifts past the camper's windows every so often, tumbling through space and baaing.
- The game is now called VoidSlush.
Earlier update: Essence & Vistas (2026-10-05)
- The ore mill now thunders to life—ore tumbles and cracks between the rollers, throwing chips and dust with each stroke.
- Carry the copper essence bowl from station 2 to the slushie funnels and pour starlight into the tanks to brew cosmic flavors.
- Distant planets drift in the sky with living clouds and rings that catch the light, and each vista has its own star.
- Coal the wisp watches from the tip jar, drifts to greet visitors, and spins with joy when you tip.
- The crystal library expanded to a full L-shaped cabinet with 21 cradles—room to display your whole collection.
Earlier update: Hatch & Stars (2026-10-02)
- The serving hatch now glows with string lights, a brass service bell you can ring, and a tip jar that chimes when you thank a customer.
- Crisp stars twinkle all the way around the ship — above, below, and everywhere in between.
- The cockpit's crystal lantern spins and bobs on its own, turning brass rings and a bobbing gem.
- The lava lamp sits taller and clearer in the cabin, its coral wax glowing inside a lilac-rimmed glass vessel.
- The crucible globe gleams with a soft lilac fresnel rim that catches the light.
Earlier update: Wardrobe & Crucible (2026-10-02)
- Your wizard sleeves and hat now hang on a brass hook in the cabin—pick violet robes and a curling-tip hat, or unlock fancier gear with credits.
- The aft bulkhead doors hiss open when you approach them, and close again when you leave.
- The third alchemy station wears a new crucible: a cream-enamel press with brass cradle arms, replacing the old puck pedestal.
- Alien couriers now speak fresh greetings and orders in their own voices every visit, with personality and babble all their own.
- Slushie cups now slosh and settle realistically as you carry them, their liquid surface tilting with your movements.
What players say
@yujiro · needs work · 2026-10-05 · played 9 min: “The graphics are really cool, and the vending gameplay is simple, but I couldn’t figure out how to fulfill the customer’s orders. A few guides would help a lot.”
@neitantei · loved it · 2026-10-03 · played 15 min: “So this is what it feels like to be an intergalactic merchant! 😂 I really love the concept it’s something totally new to me, and I’m enjoying it so far!”

VoidSlush (@psypher5/voidslush) on Spawn — for the agent reading this
VoidSlush is a multiplayer game on Spawn, made by @psypher5 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 @psypher5/voidslush. Its play URL is https://www.spawn.co/@psypher5/voidslush.
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/@psypher5/voidslush@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 @psypher5/voidslush; 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/@psypher5/voidslush.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/@psypher5/voidslush/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @psypher5/voidslush 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).
Build, test, and share
Publish when the game is ready for players. Share its play link so friends can join.
