It sounds strange, and it is, but it works. The controls are responsive, the graphics are colorful, and the game perfectly captures that "one more try" feeling as you ascend through the seven levels, climbing up on the fallen objects all the way to the top of the sky. There are lots of coins, med packs, and extra lives to collect as you go, but the tough part is just staying out of the way -- three hits on the noggin costs you a life (and gives you a trophy to remember what wacky object killed you). There are many, many objects in the game, too, and you'll undoubtedly be surprised by what falls on you next.
It's a great game, worth every cent of the US $1.99 they're selling it for in the App Store. Terrific little indie games like this are what make the iPhone platform really shine.
