I made this prototype to learn how to use the native 2D support that came with Unity 4.3. I'm surprised it took this long for them to support the 2D and 2.5D developers, but better late than never. In this demo, I incorporated sprite animations, pathfinding around the lake, camera panning, and a custom pixel shader for swapping out colors on your sprites. I really love Unity. It's free, the asset store is a great resource, the community is super helpful, and it's free.
