Travel through a five-part course by car and by plane, either by yourself or racing an opponent. I combined all the Prototype 1 bonus features and the plane challenge into one game and added some other features like a game over screen and the ability to select one or two players. Honestly, I probably got a little carried away and probably spent way too much time on this, but I did learn a lot by doing it, and now know how to do several things in Unity I hadn't known before.
