Excellent game with a very fun play style. It challenges you for sure, but I did beat the game and 3 star every level pretty quick. Afterward I just stopped playing because it didn't have the best replay value for me. Otherwise it's great and fun for kids. For instance, I noticed one day that my coworker's son was playing this game. He was not nearly as far along as me, so I asked if I could play and he was seriously impressed with how good I was at it because I beat a level he was stuck on. So it's probably just more for kids. Some more levels or something would be nice though!
