Nice audio and the simple graphics with the cool particle effects made everything clear.
It would have been nice to tell how the scores were calculated. I wasn't sure if I was supposed to shoot the ducks until they finally exploded because they took a lot of hits at the end and it seemed like every time I hit one it dropped and egg and my score went down. That made me believe that I was only supposed to shoot the blue ones and make them yellow/red. I'm still unclear exactly what I was supposed to be doing.
