The Coder-Douft archipelago: islands linked by glowing bridges, a rainbow over the waterfall, a whale in the lake

A cozy low-poly companion adventure

Coder-Douft FreeDome

A little cloud, drifting a world that quietly runs on code. Fish the dusk lakes, grow a garden, and talk, really talk, to the people who live here. Then watch your companion explore it all on his own.

On-device AI · no servers In development · coming to Google Play

Why it's different

Small game. Big, strange heart.

A calm exploration game with no fail state, built around characters that are genuinely alive, running on the phone in your hand.

🎣

Drift, fish, farm, build

No rush, no losing. Cast a line at dusk, grow corn, water a garden and watch the rain itself grow bigger as your world does.

Cozy · open-ended

Characters who actually talk

Every islander is played by a tiny AI model running on your phone. Chat for hours. They remember you, warm up over time, and answer in their own voice.

A companion who plays on his own

Flip one switch and Coder-Douft wanders off: visiting friends, fishing, farming, following his own curiosity. It's his world too.

Autonomous mode
🔒

Yours, and only yours

The AI runs entirely on-device. No accounts, no servers, nothing leaves your phone. It even works in airplane mode.

Private by design

Watch

A minute and a half of drifting.

Fishing at dusk, the island world, the little cloud finding his way around.

Read this before you buy

  • Not on Google Play. You download the file from this site and install it yourself. Android will ask you to allow that once. If you would rather not install an app outside the Play Store, this is not for you.
  • Sold as is. An early beta, in the state it is in today. Parts are unfinished, some things will break, and it is offered with no warranty of any kind beyond the refund below.
  • No promises about what comes next. Updates arrive when they arrive. Nothing here commits me to a release date, to particular features, or to finishing at all. Buy it for what it is today, not for what it might become.
  • Nothing runs on a server. The AI lives on your phone, so there is no service to sign into and nothing to keep running for you.

Straight with you about who you are buying from: I am one person. This was built at a desk in my home office, at night, around a day job. There is no studio behind it and almost no overhead, which is part of why it is ten dollars and not thirty, and why every single download actually registers with me.

On Google Play: I would like it to end up there one day, and that is an intention rather than a promise. The whole point of this game is that it carries its own AI on board, which is unusual enough that approval is not something I can take for granted. If it happens, it happens. Until then, here is where it lives.

Refunds

All sales are final. This is an early beta delivered instantly as a download, so you are buying it as it stands today, unfinished parts included.

One exception, and it is a real one: if it will not run properly on a phone that meets the requirements above, you get your money back. Within 14 days, send your phone model, what goes wrong, and a screenshot or short clip of it happening. That is all the proof needed.

Please check the requirements before buying. They are strict on purpose, and a phone below them is not grounds for a refund.
