The look of the DS version is decidedly different than the GameCube or GBA. All of the menus and HUD icons are done in a very artistic, minimalistic cartoon fashion. They only use two or three muted colors to depict Remy, or any other character, for that matter. The actual in-game characters have plenty of color and look characteristically like rats. But, some of the background colors will wash the detail out quite often.
The music is decidedly less like a movie score, as well, giving way to repetitive tracks that can be a little distracting. Sound effects are not high up there either, as they fall into the canned and repetitive category as well.
