Summary: This game uses all functions of the DS well. The gameplay takes place on the bottom screen with the top screen being an extension of the scene (also the help tips appear here). You can play as multiple different characters. You use the directional control pad (or the ABXY buttons for LH gamers!) to move each character (although the game is set in a 3D world, the actual gameplay is only 2D so you can only move side to side or up and down).
