Shooting as many ducks as you can within a chosen timeframe is your mission. When you start a game, these ducks are flying all over the place in a landscape that was so peaceful. The points you get for every shot down duck depends both on how fast and diagonal they fly. If you reach a highscore, you can submit your score. Each available timeframe has separate highscores which will be stored in your phone and can be listed. Above all, the app is free now, so see if you like it.
