in your browser.
The current early alpha runs right on this page. The first launch loads the game data; after that, you can tend your little worlds without installing anything.

✦The spheres are being prepared.
If this is the first Web release, the game will appear after the next successful publication.
Still an early alpha.
Content, balance, and browser compatibility may change. For the most stable desktop experience, the Windows version remains available.
Technical note.
A current browser with WebAssembly and WebGL 2 is required. Audio begins after your first input inside the game.
