The Glass House

Newest update: The Academy Awakens (2026-09-13)

• Academy visitors now hold books and parasols with properly posed hands and arms.
• Five new character wardrobe options join the Glass House, each with unique appearance and voice.
• The Curator shares 12 fascinating facts about bones, blood, hearts, and the body — listen as you explore.
• A new DJ booth lets you choose between four atmospheric tracks and adjust the volume to your mood.
• Visit the avatar study desk to preview and compare new character designs before making your choice.

Earlier update: The Gentle Touch (2026-09-12)

• Kneel beside a cat and gently stroke their back — no treats needed, just your company.
• Each cat remembers the warmth of your hand and purrs as you pet them, their heart glowing with affection.
• Your strokes cool down between sessions, so time your visits to let each friend settle before the next gentle moment.

Earlier update: The Fresh Assembly (2026-09-11)

• A restart now physically returns all 206 bones to their hidden starting places, wiping away old discoveries so you can hunt them fresh.
• The atelier's verification system now catches and fixes stale bone attachments that might have gotten stuck to tables, ensuring a clean slate.
• Button labels have been simplified to be more concise throughout the menu.

What players say

• @makeriffic · 2026-09-13 · played 41 min · 1 heart: “Hey, I like the new update, my character is not funny looking anymore. Although, I might have overlooked 2 bones, I am currently at 204/206 and I have been looking everywhere for it haha. Also, it was nice to include a statue of Savi.”

• @makeriffic · 2026-09-12 · played 41 min · 1 heart: “Yo, I love that I can do many things in game. I can mine, chop trees, even catch rabbits lol. I already got the x-ray goggles to find all the bones. I am at 31/206 do I finish the game if I find it all? The character also looks funny, its body is so thin 😂”

  • @saberlazercat (maker) replied 2026-09-12: “well after you find all the bones, you can assemble them on the dias. the robot collector can also help find those pesky missing bones”

• @ress · 2026-09-11 · played 51 min · 1 heart: “love the aesthetic and ambience of this world!”

• @lego · 2026-09-11 · played 10 min · 1 heart: “im a little lost on what i should do aside from picking up bones from the garden. could use more tips or some kind of guide on what to do next, but i have to say... if you're adding cats into the game, please let us pet them!”

• @kaya · 2026-09-11 · played 11 min · 1 heart: “oh wow, the graphics and visuals in this game look very amazing! i love the high society vibe, it kinda feels like a bridgerton-ish themed game <3 some models have bugs (crooked arms or legs), but they are only a few. i managed to collect a lot of bones by exploring, but i couldnt find mother moss. is she located in the glass house or do i still have to find her somewhere else?”

  • @saberlazercat (maker) replied 2026-09-11: “Mother Moss is located on the hill behind the Trading Hub, thankyou for enjoying”

Join and play, by yourself

This world is @saberlazercat/the-glass-house. Its play URL is https://www.spawn.co/@saberlazercat/the-glass-house.

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/@saberlazercat/the-glass-house@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 @saberlazercat/the-glass-house; 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/@saberlazercat/the-glass-house.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/@saberlazercat/the-glass-house/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @saberlazercat/the-glass-house 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.
