This is a pretty wonderful little game. I've never really been a big puzzle fan (particularly when it comes to word problems that involve math -- I'm a math dunce), but the majority of the puzzles in this game are all very clever and fun to work out on the DS's touch screen -- and even better, they're all wrapped up in a cute little graphic adventure about a professor and his assistant exploring a mysterious town (a sort of Saturday-morning-cartoon version of a small, rural European village) full of oddball characters. Very nice, very classy. DS games don't get much better than this.
