My problem with this game, is that the blue noises (boss ones)are way too hard to beat on hard. That kind of wrecks it for me, after finishing the story-line of course.
The game is the best on the DS definately IMO.
Also, what is mingle mode? I never found out what it is (and no sites seem to tell me how to mingle, just benefits)
