Android game: Pengi and the Polar Pirates

Hi,
I just released my first game for Android, it is made with Unity3d.

Check it out in the app store: https://play.google.com/store/apps/details?id=com.NoorStudios.Pengi

Here's the plot:
Help Pengi save all penguins from the evil Polar Pirates.The Polar Pirates are terrorizing penguins all over the south pole. All efforts of stopping them has failed, and the penguins last hope rests in your flippers. Armed only with snowballs and whatever you may find on the road, you must slide your way through the frozen lands of the South and fight the pirates where ever you find them.
