This is the same game that you'll find on GetJar, with all 175 levels and the almost annoyingly cute main character, Om Nom. The only difference is that the version in the Android Market is 99 cents and is ad-free, while the GetJar version is free, but has ads. So, if the Android Market is your only way to get the game, it would seem the choice has been made for you (because this is a great game, and 99 cents is pretty reasonable.) But, if you want to try the game before you buy, you can still get the free version from GetJar, or borrow your friend's iPhone, because we're pretty sure they'll have it.
