Nice idea. I like the simple 3D art/graphics. Will be good with a bit more polish to the gameplay.

Cool Concept. 

Even with the camera at a strange angle its enjoyable to play with the UI bar for the charged shot. 

As the game is not fully to a standard I wont be critical :P 

Adding some screen shake when you hit the trees would be cool and trail effects on the long that react to the speed/power of the throw would make it cool. 

Keep up the good work. Can't wait to see a updated version.
