Very repetitive, but not that bad...
You have to go through many levels. To complete a level, you first have to collect a specific number of goodies. Then you have to find the exit. The levels are very big and confusing, especially the later ones. Sometimes you have to beat bosses to move to a new world. The only things that change when you reach a new world are the level graphics, enemies and the look of the goodies. Nevertheless, this game is not that bad. You can have fun with it, but you will end up being confused by the levels at least for a few times. I have seen better games, but there are games which are more worse than this one. This game is not the No. 1 choice for gamers, but you can have at least some fun with it.
