This seems like a great concept. Rather than trying to fit existing games to the touch control system he appears to have started with the controls and then matched it to a game. This reminds me of the way that the best Wii games are the ones that work with the controller as opposed to forcing its use in someway. I wouldn't be surprised if this isn't already in the works, but if not why not.
A Nintendo DS version might be more marketable and get a lot more income!! But we might get a port in a year or two!😀
