Terrarium.

A pocket voxel world floating in the dark. The terrain grows itself from noise when you arrive, block by block; trees rise where visitors tap; paper birds commute between the canopies and fireflies come out once the building is done. Drag to spin it. There is no goal, only a small place that keeps you company.

A little world. Leave it different than you found it.

Drag sideways to spin the island. Tap any patch of grass and a tree grows there. The birds will find it.

Bench notes

The build
The island is a heightfield grown from layered value noise, shaped by a radial falloff so it tapers to a ragged keel, with a pond carved at the lowest interior point. Every voxel is an instance of one cube; the whole world is a handful of draw calls, which is why it runs happily on a phone.
The inhabitants
Trees are procedural: a trunk, a canopy blob, a few blocks skipped at random, some blooming coral. Birds follow a two-state life of perching and flying, picking a new treetop when they get restless. Nobody is scripted; the world just runs.
The manners
The canvas only claims horizontal drags, so scrolling past it always works, and with reduced motion on, the island arrives already built and moves only when you move it. New island regrows everything from a fresh seed.
