Just played it. Fun game. Here's what it's missing...

First time I loaded it the menu seemed sluggish. When I pressed buttons, the button gave no feedback and I wasn't sure if the click had registered. I understand there's loading time involved, but some feedback would be nice.

During game play when I "Shoot" there is nothing that displays a shooting event. Balls just explode if my cross-hares are on it. That seems odd. Again, a feedback issue.

Also the menu buttons seem smaller than needed and there are too many options. If you could make it simpler that might be better.

Overall the game play is smooth and the gyro controls are cool. I think this would make a really engaging first person shooter. Maybe shooting something other than balls for points would be more fun.
