Originally created by a solo Lithuanian developer as a prototype for a motion-sensing camera before transitioning to traditional controls, the game became a major commercial success partly through streaming popularity.

This game features a wonderfully subdued world, an intriguingly voiced narrative, and things that are really weird.
