Kodama's Home

Newest update (2026-09-10)

• Added a small bottom-right Reset button with explicit confirmation. Start the current save from scratch—including repairs, comforts, kodamas, recovery checkpoints, story, music timeline, and first-play guidance—without affecting other saves or players. Includes the latest Work/Grow styling and forward-only story polish. Existing progress stays intact unless its owner confirms Reset.

Earlier update (2026-09-10)

• Singleplayer fix: each player now has an isolated temple, progress, story timeline, music and save slots. Existing saves are preserved. Includes the larger rounded Work/Grow buttons, transparent icons and forward-only story reading.

• @mistarpudding · 2026-09-10 · played 42 min · 1 heart: “i just saw that you added a singleplayer fix, but when i entered the game, 89/100 things were already mended and i already had 12/15 kodamas in my game so i had nothing much to do anymore. is there any way i could reset the progress? really love the game's design btw! and the song that played at the end made me feel emotional <3”

  • @op_nico (maker) replied 2026-09-10: “Thanks man, I have no idea if I can do something, maybe I can ask Mavi to add a sbutton in the bottom right corner to reset all progress, gonna do it now :)”
  • @op_nico (maker) replied 2026-09-10: “Done, reset button added, thanks for pointing that out :)”
  • @mistarpudding replied 2026-09-10: “thank you! i was finally able to play from the beginning. kodamas are starting to come as i built their home. really love how its been going so far. and the graphics with the lighting looks so nice!!”

• @lego · 2026-09-08 · played 24 min · 1 heart: “im expecting something cozy but i got something else in my eyes instead. i love the visuals tho, and the music is so good that... oops, something got in my eyes again”

  • @op_nico (maker) replied 2026-09-08: “The story and the ending should be something n the eyes as well lol, hopefully at least! If the game ends up hitting the right spot it could be memorable :) Thanks for trying it out!”

• @makeriffic · 2026-09-17 · played 17 min: “Yo, I was looking for just a cozy game, but instead I got an emotional one 😭 I have just upgraded my first hall. Can you make the work journal stay also like the grow journal screen? It was pretty time consuming having to press the work on the left then pressing one work at the right then repeating it lol.”

• @lego · 2026-09-08 · played 24 min: “😭 i finished the game, but tbh all i really did was buy/place 2 things and after that i couldnt really spend my money anywhere else. the story still progresses until it ends”

  • @lego replied 2026-09-08: “oops. i didn't click reply. my bad”
  • @op_nico (maker) replied 2026-09-08: “Thanks for completing the game! I can't believe someone managed to finish this already! I am currently trying to make it more understandable. For the endgame I was thinking about making more and more room to create and customize. I hope I'll be able to squeeze than in by tomorrow's release! In the meantime I hope you enjoyed the story :)”

Join and play, by yourself

This world is @op_nico/kodama-s-home. Its play URL is https://www.spawn.co/@op_nico/kodama-s-home.

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/@op_nico/kodama-s-home@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 @op_nico/kodama-s-home; 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/@op_nico/kodama-s-home.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/@op_nico/kodama-s-home/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @op_nico/kodama-s-home 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).
