STANDBOX is a single-player physics sandbox with one job: Stanley, a ragdoll who stands, wobbles, falls, and keeps heroically trying to get back up.

Chaotic
A colorful voxel sandbox where you start with bare hands and end up engineering farms, machines and whole landscapes. Mine, craft, cook and build at your own pace in a bright open world, alone or with friends. The kind of game where one more block turns into five hours.
