fun i have this one. it can be fun at times but you can really beat the game by just pressing the attack button. the items and special moves are really fun. like when Keroro does his Kamakazi attack. there are also alot of weapons like a rocket launcher and some other wacky items. pretty funny stuff. i got stuck on level 5 but i figured out how to do it by talking to a guy who wrote an FAQ for it. have not booted it up since then. it must be really fun with 4 players.
