everything he says....

plus the cannon control sucks

Good Start

The game itself is always a good one, but the way you have done it was poor, sad to say. There was no animation for when you hit the person, or even when you won, it was just "Okay, shoot until you hit it and then do it again". The point system was hard to understand as well or even see, which would have been better to let the people know that it is time-based (I think). The last thing is the levels. I got tired of seeing basically the same thing over and over again. Maybe try to add variation in the levels in the respect of the cannon's location and the overall background or objects in the game. This game would have been much more fun if you spent just a little more time on it, I believe.
