Mighty Flip Champs is great. I was a little confused at first with the lack of jumping, crouching, and the usual platforming fair, but it all makes sense after playing the game. It's a puzzler through and through. I wondered what the point of the touchscreen creating a box on the screen was until I got to some boards with four different flips to them. Having the box there is a life saver when trying to remember what square you're trying to get to.
Long story short, if you like puzzle games, drop the $8.
