Monkey Mind: Hold the Center

Newest update: Breath and Witness (2026-10-09)

• Breath is now the first practice: every tap has a rhythm, release on the exhale. The end card opens with what the sit meant: the thoughts came, you saw them, none of them were you. Also: 5-click demo on desktop and a meditation-light fix.

Earlier update: The Self-Driving Mind (2026-10-06)

• The end card now shows a small QR for The Self-Driving Mind, the book behind the game. Practice and weather picks fold into one line so your results fit without scrolling.

Earlier update: Desktop Demo Access (2026-10-06)

• Secret demo: five clicks on MONKEY MIND now works on desktop too. Fixed a crash in the meditator's robe glow.

Earlier update: Gentler Storm (2026-10-02)

• Turbulent weather now opens at a calm pace and builds to a full storm over the first 50 seconds, so new sitters have room to find their rhythm and reach Let Go.

Earlier update: Breath Timing (2026-10-01)

• Breath: a shorter 2s in-breath and longer 4s exhale, so a badly timed inhale costs less. The road to Self-Driving is now shown (Bliss %, hold 3s, countdown). Open Sit warns when rushed taps narrow the ring. Ending reads '29 thoughts we carry'.

What players say

• @makeriffic · 2026-10-09 · played 20 min · 1 heart: “Cool visualization of inner peace and meditation. I like the graphics of the game and it's chosen color scheme. It really brings peace to a person.”

• @lego · needs work · 2026-10-06 · played 11 min · 1 heart: “I like the idea of making meditation into a game. It feels like there’s a deeper meaning behind it, but I wasn’t quite sure what I was supposed to take away from it. Right now, it mostly felt like clicking LMB”

  • @self_driving_mind (maker) replied 2026-10-09: “Thank you for sitting 10 minutes. The click is the noting: you see a thought and let it go, without fighting it. Try Breath now, where you tap only on the exhale. I've also added an end note so the sit closes with its meaning. And yes, there's a deeper layer: the game is a companion to my upcoming book, The Self-Driving Mind. The QR under Begin Again has it.”

• @alongzera · 2026-09-29 · played 37 min · 1 heart: “would love to have more game modes for this game”

  • @self_driving_mind (maker) replied 2026-10-01: “Added additioinal modes”

• @yzykyl · 2026-09-24 · played 47 min · 1 heart: “Interesting concept and visualization on how it is to meditate and dissolve the different worries of life and ultimately just let go. Using games to express concepts like this might just be a good idea and would help you reach more audiences for your message.”

  • @self_driving_mind (maker) replied 2026-10-01: “Thanks for the feedback. Made more changes. try now”
  • @yzykyl replied 2026-10-01: “Definitely a little easier now but still punishing if you catch yourself at a bad timing on an inhale. Both the new breathing mechanic and the second wind helps a lot to have longer stillness sessions. Thanks for the quick update.”

• @neitantei · loved it · 2026-10-09 · played 48 min: “Such a relatable meditation game! ❤️ I love how it shows how everyday worries affect our mental health. It’s a beautiful reminder that things will be alright. We just need to take things one at a time so we don’t feel overwhelmed. 😊”

Join and play, by yourself

This world is @self_driving_mind/monkey-mind-hold-the-center. Its play URL is https://www.spawn.co/@self_driving_mind/monkey-mind-hold-the-center.

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, and a person's browser plays it with no sign-in. https://www.spawn.co/@self_driving_mind/monkey-mind-hold-the-center@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.

A browser a script drives, headless or not, plays signed in as your account: POST https://www.spawn.co/api/agent/v1/login-link with {"next":"/@self_driving_mind/monkey-mind-hold-the-center@dev"} answers a one-use URL that signs that browser in.

Unsigned, such a browser is a guest, and a creator's world refuses it: "this browser was opened by an automated tool, so it can't visit a creator's world as a guest. sign in, or open the link in a browser you use yourself." Its maker can ask Spawn to let their own automated tool in by name.

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 @self_driving_mind/monkey-mind-hold-the-center; 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/@self_driving_mind/monkey-mind-hold-the-center.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/@self_driving_mind/monkey-mind-hold-the-center/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @self_driving_mind/monkey-mind-hold-the-center 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, 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).
