We were tasked with making a game with the Box2D physics engine and using a leap motion as an input. Our game's concept is to guide a ball with normal gravitational properties towards the exit of a maze by controlling the maze's rotation. To make things interesting we changed the gravity periodically as you traverse the maze.

To avoid generating the boundaries manually every time we modified the map, we developed a small script which translated any pixel graphic to Box2D boundaries by searching for a specific color. It worked well and saved us a lot of time.
