A couple thoughts :
a) The game has a genuine sense of humor, and I love the way that the physics work perfectly.
b) There's nothing you need to actually add to a Windows game, in order for it to be controller-friendly. If all a game has are keyboard defaults, those can be plugged into profilers (like JoyToKey) which support hundreds of controllers. It would be nice if the game automatically went into fullscreen on startup, and if there was an actual keyboard key for exiting, besides Alt-F4.
