this is a sort of classic arcade style game i would really like to play, with a variety of critters, a fun theme & lots of events. it also has the collectable type theme, with trying to gather all the fiends & their enhancements. IT REALLY BURNS ME HOW MERCENARY IT GETS... you start off doing pretty well without having to spend TOO much, and supposedly there are 6000 levels , but after about level 2000, it starts to get where you can't pass a level without spending for boosts or powerups or extra moves, etc.
