I'm the type of person that can play a game for a while to see what's to come. The levels do get more difficult and definitely a challenge when you get to high levels. it's a great game to kill time without too much thinking. There are many different kind of games for different purposes. Some you play to exercise your brain, some excite you, some relax you and some you just play for the hell of playing it. For what it is, it's great and it's cute!
