Bitmochi

A pixel pet that lives in the panel and wanders its room in real time. Feed it, play with it, clean up after it, watch it grow through an egg, a baby, a child and one of three adults decided by how well you cared for it — and if you neglect it long enough, a small ceremony and a new egg, with a generation counter that never resets. Pixel art, drawn at a whole-number scale so it stays crisp at any panel size, in a panel that takes your theme's colours. No network, no accounts, no telemetry.
