Boss battles intense is hell. I can only kill 7 bosses. LVL9 Characters are easy, to me. I beat them all yesterday on my first try...that surprised me, since I usually lose to Pikachu, Olimar, Mr.Gay & Watch, and Wario. So that was an acomplishment for me. Adventure mode is also hell. I got through the Forest with only Lucas cause everyone died at the begining XD
