Spinning Wheel Hero

This is my first game. All criticism appreciated.

In this game, you control a cannon and your goal is to hit the spinning wheels. Depending on the region hit, you either get beneficial effects or negative effects. You can see the effects of all regions within the game itself - during the fight, hover over the rainbow object in the middle-right area of the screen. 

Everything related to sound can be changed in the main menu's options menu. 

Recommended to be played in a Fullscreen mode.
