TPG says, "Buy it. Hell, buy two!"
"When this game was originally described to me, I had no idea how it would be achieved. A 2-D platformer on the top screen, and a match-three puzzler on the bottom. It may be hard to visualize, but it got my attention. I'm glad it did. This is the first must have DS title of the year, and the best I've played since Professor Layton.
The game may be a little bit easier to explain if I try to do it only one screen at a time."
