The only flaw in this game is it's short plot. Adding another villain or two would have been nice. Toot was bound to die anyways. Finally, some may complain about the easiness of the game when acquiring "guided missiles" aka Explosive/Homing, but I think it is a necessity in the sudden increase in difficulty. When the players are finally given power they complain, so i think it would be ironic to remove these features as they were honestly waited for. Besides, Lightning/Piercing is a boss killer, are the game designers going to have remove even the basics just to satisfy the never-conforming gamer?
