FAQ

Will my island still be here when I return?

Yes. Terrain and decorations auto-save to dedicated storage in this browser. They do not transfer to another device and disappear if browser data is cleared.

Does the lo-fi music stream an external recording?

No. Soft chords, breeze and bird chirps are synthesized in real time on your device with Web Audio and can be muted at any time.
