That game is purely for touch UI since the main mechanic is to do a swipe.
You'd use a controller to run the browser in a console?
Game is 99 cents on iOS and free on Android isn't it?
Works fine with a mouse too Should they ever manage to get HTML5 working properly on 360 and PS3, then Kinect and Move would make fine interfaces for this game as well I reckon.
Anyway, it is very promising that this is running quite smoothly on Google Chrome, FireFox and Internet Explorer, as that seems to suggest that HTML5 is indeed a valid alternative for Flash at least for these types of games.
