Dr Rudy 2 is a semi-sequel to Kevin J North's original Dr Rudy game (which was not too original to begin with, having unashamedly ripped off Nintendo's Dr Mario.) In Dr Rudy 2, the object is still to clear blocks, but this time you do so by bouncing your constantly moving ball off them. When your ball color matches the color of the blocks the are eliminated. It's a somewhat difficult but entertaining diversion.
