I just finished this. And though I wish it were longer, it's still near the top of the list when it comes to best platformers for iOS. It's not a lot of crazy action, but rather more subdued lite puzzle elements and platform jumping as you try to make your way past various obstacles to reach the next level. I actually found the calmer pace to be more absorbing than other, more hectic titles. And that's especially true when including the beautiful graphics and music. The controls also work very well.
I only paid a dollar for it, and I feel that it's worth more than that. Of course, that's up to the individual, but I do highly recommend the game, and certainly platform fans shouldn't miss this one.
Pros: Great game. Atmospheric and highly polished. Very fun to play.
Cons: Lacks a bit of environmental variety. Not very long. You will be left wanting more.
