The 2D Universe is at your fingertips. Experience Newton's Law of Gravitation in a beautiful, retro feel. Kepler Orbit is a physics sandbox built on an engine to simulate gravitational attraction between masses. With just a touch, spawn a new mass and be amazed! Create stunning visuals and patterns with two types of pathing for each mass. Control and alter natural physical properties with rebounding, absorption, negative-gravity, and directly changing how forces are calculated. The power of the 2D Universe is in your hands.
