Just Another Day

Newest update: Renderer Refresh (2026-07-14)

• The starfield dome now renders as scattered geometry stars instead of a texture, staying crisp and visible in the new engine.
• Lava surfaces churn with restored domain-warped heat fields and cooled plates—the sun and lava pools now show their full molten detail.
• Portal wisps flicker with lighter computation, so older GPUs can handle the effect without choking.
• Basement ceilings stretch taller and the hatch widens slightly, opening up the facility's underground spaces.
• Glass surfaces and materials throughout the world have been refined for the new renderer's lighting model.

Earlier update: Down Below (2026-06-11)

• A hidden black button reveals a terrible choice — press the wrong one and the basement hatch seals forever.
• Descend a long steel staircase into a basement filled with forgotten tools, machines, and cryptic notes.
• Discover a time machine waiting in the depths, its keypad dark and its purpose unknown.
• The basement holds the key to everything — but the path downward is one-way.

Earlier update: The Poster Shift (2026-06-10)

• A weathered apocalyptic poster has moved deeper into the facility, repositioned along the wall.
• The vintage urban decay imagery now hangs in a new location—still watching over the space, but from a different vantage point.

Earlier update: The Facility Update (2026-06-10)

• Explore a new office space filled with posters, desk lamps, and unsettling details that hint at something darker beneath the mundane.
• Discover what the facility was used for through environmental storytelling and hidden clues scattered throughout the main area.
• Interact with new readable objects and puzzles that deepen the mystery of Just Another Day.
• Notice the small details—a toppled chair, flickering lamps, pixel art frames—that suggest something went very wrong here.

Earlier update: The Blackout (2026-06-10)

• The lights cut out mid-escape — darkness swallows the facility and you with it.
• Shadows now hide threats you can't see coming, forcing you to move blind or find another way.
• New narrative unfolds as the blackout forces you to confront what's really happening in this place.
• The clock keeps ticking even when you can't see it.

Join and play, by yourself

This world is @abbidabbi/just-another-day. Its play URL is https://www.spawn.co/@abbidabbi/just-another-day/play.

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/@abbidabbi/just-another-day@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 @abbidabbi/just-another-day; 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

This game runs an engine from before 6.0 and has no repository to clone. Its creator can open https://www.spawn.co/@abbidabbi/just-another-day/code for upgrade instructions.

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.

Ask to build with the creator: POST https://www.spawn.co/api/games/<appId>/crew/ask. They approve from their bell. The code page offers an invite prompt after the game moves to 6.0.

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.
