Idle Craft 3D

Open Idle Craft 3D and you are playing — a Boys game that runs on the page rather than beside it. Designed around touch input, and comfortable on a small screen. Tagged 3d, 3d games, boy, boys, fun.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Everything runs client-side, so there is nothing to set up before you start.
