This is my first app, and though I blew it out of it's original scope (it was supposed to be a simple clone of this game), I think I did a decent job. It was a great learning experience, too, and next time, I know not to do certain things (like write a movement and collision detection system from the ground up).
Regardless, the main point of the game is to live for as long as possible, and dodge the falling tikis. The game itself can be found here, and it's completely free. Also, if anyone encounters a movement bug, can you please tell me what appears to have caused it? I got two reviews complaining of one, but yet, I never found it, even though my brother and I played it a lot.
Here are some screenshots (they represent the game's more peaceful moments, though, as it's near impossible to press the home and sleep buttons during more hectic parts):
