Human: Fall Flat is a physics-based puzzle platformer where players control a customizable wobbly human character named Bob. Using intentionally clumsy arm controls for grabbing, climbing, and interacting with objects, players navigate open-ended levels that each contain multiple solutions to their puzzles. The game supports up to eight players in online or LAN multiplayer. 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.
