Fun game, even if it's not the most outwardly creative or innovative thing in the world. It handles well and despite what other people have said, the 'turn to stone' controls are pretty responsive and you can actually do them while partially touching spikes, so it's pretty darn forgiving. The game is incredibly easy to beat and only slightly harder to three-star on every stage. If I had to give an award to the hardest level, it would the the deceptively tricky level 22 (hint: Use the lines of the background as a grid; a creature can jump exactly the height of one of those large background squares). So, yeah, not bad.
