Kanso

Build a calm, meditative 3D browser game inspired by "Kansō": the player cultivates a living digital bonsai tree in a beautiful, quiet scene.
Tech: Three.js, single page, loads instantly, no login. Works on phone (touch) and desktop (mouse).
Core loop: the tree grows procedurally over time (branches and leaves generated from simple rules or noise). The player shapes it: tap/click a branch to prune it, and tend it (e.g. watering) to encourage new growth. Nothing is lost or failed; the goal is a tree you find beautiful.
Mood: soft lighting, slow orbiting camera, gentle ambient music and nature sounds that start on the first click. Minimal UI, no timers, no game over.
Save the tree in localStorage so it is still there next visit.
Steps: 1) render a pot and a procedurally grown trunk, 2) add branch growth over time and pruning on click/tap, 3) add lighting, a scenic backdrop and sound, 4) add your own twist (seasons, different species, a zen garden around it).
Make it your own: don't copy the original's name, art, text or code.
