[Android] Free: Highwind (was $1.59) @ Google Play

A decently rated game, now free on the Google Play Store!
Enjoy :)

In Highwind you control a paper plane using only two buttons. You will destroy enemy planes and protect your own. Tapping the right side of the screen will shoot bullets and holding the left side will activate the shield. The shield blocks and reflects bullets back to your enemies.

Fight different enemy planes and obstacles, each with different behavior. Travel to different dimensions and avoid obstacles on the way.

As you progress through the game you will be able to purchase upgrades to your health, shield and ammo. Also, each time you beat a level you will get a power up that will help you defeat your enemies.
Each time you play you will accumulate points that will unlock new planes and new game styles. Try to beat the game in each one of the different styles!
