Gnu Revenge

With more than 70 levels and the obsessive quest to save all three Gnus on each of them (much like collecting stars in similar games), you're going to spend a lot of time finishing and perfecting your Gnu rescue operation. This is some of the best physics-based puzzle fun I've had on my iPad since Angry Birds, and unlike that game, this is all about skill, speed, and momentum, more than chaos theory and random bits of crumbling architecture. Gnu Revenge is an instant classic and soon-to-be family favorite.
