Cool idea. Needed to be harder in my opinion. Maybe adding more Crosshairs, shooting at the ducks as rounds go on, or the dog appearing trying to snatch up the bird. Sound effects could have been louder, as I often barley heard the gunshots. Lastly UI indicating changing rounds, and winning/losing rounds would have been helpful. That's all, I really liked the concept, and you picked a great game to implement the theme for.
