Yep, I got this game a week ago, and I'm impressed by it, its an RPG really, I like the cartoon style and the monsters are completly creative. The moves are strange, If its from an normal attack, to using cheese, or throwing rocks, or using sex appeal.
Not a great rent, this game is long as hell, you should just buy it.
