I'm starting to realize that radically diverging from the built-in API's is probably not a good idea, since basically it becomes 2 API's I have to maintain and online references would be like JavaScript where there's always a jQuery answer and a normal JavaScript answer. I'm going to wrap the Game/Gamepad API's, but allow direct access to the Graphics2D and Audio libraries. This especially makes converting non-TwoCans to TwoCans difficult. Since I chose the scene management approach for the SDK, what I'll do is still include it as an optional (and highly encouraged library) for those writing code from scratch directly for TwoCans. </li><li> I'm going to change the build file format from XML to JSON.
