Physball is a level-based, physics-based 3D puzzle platformer written in Rust, using the Bevy Engine. Physball started as a test game written in Bevy, called ball-thing. Ball-thing was just an experiment of rolling a ball around a 3D physics world that unintentionally followed in the steps of many other Marble Blast clones.
