Well done
I don't understand some of the reviews... maybe they played a completely else game or stopped after one minute. The rotation and zoom-thing was very well done, though the wole game-Idea is old (but if that was a counting criteria at NG we had 98% games with low rating). It was just a bit hard to see at what you are aiming when the rotation speed was very high, maybe you should make the guideline thicker or something.
What I liked most was the music. The menu-music has something exciting, and the ingame-music seems to work together with what happens.
