playing this on a Wii U only shows that this game doesnt use the DS potential as well as it could have. the duel screen is more of a gimmick than anything else, and outside of the two extra buttons, this couldve easily been a gameboy game. despite these issues, the game is still great. the worlds are interesting, the gameplay is satisfying, and the music is amazing as always. if you like the Mario and Luigi games, youll like this. just play it on its original hardware
