Fullscreen advised(On windows while in fullscreen do fn and f11 to go full fullscreen which will improve performance even more.) This is an advanced physics engine. Drag scratch cat around and see the physics. Space for next object NOTE(please read): Ball physics are very work in progress and are currently very unrealistic. If you are using this for teaching purposes then DO NOT use the ball as it will teach students the wrong thing. Updates coming soon: Proper more realistic ball physics, More objects, More backrounds,
@Funut made a tutorial CHANGE LOG: v1.1.1: -Disabled physics for ball v1.1: -Added new objects: Square, Rectangle, Triangle and Ball(Read note) -Upgraded a few features v1.0: Release
