can only agree with what is said so far. Its certainly a nice game with slick 2D graphics and nice tunes, but it is so easy it ain't funny anymore. Only the title song is anything remotely like Huelsbeck's work also, the other tunes are only inspired by. But they still fit very well with the game!
New Super Mario Brothers is still the king of the DS platformers for me, at least that one is a right chore to finish, but not as frustrating as some of the 3D offerings (Mario64 DS.... GRRRRR!)
