It's alright. I would like some instructions on how to fire a bullet though.

I am a duck and I find this offensive.

Now that that is out of the way, let's talk review.
First of all, the animating itself wasn't very good. I'm not saying that's a huge deal, but it wasn't too pretty. Atleast make the background different from a solid colour.
Second, the gameplay wasn't good either. Simple click-to-shoot-movieclip mechanics is frowned upon, I'd say.
Now, it wouldn't be too bad if it didn't lag like hell. Because of that, I can't even hit the fast ducks that often.
In total, I give you 1 star. I suggest getting better animating skills, fixing the gameplay issues, and overall making it more appealing. Also, make more levels and a main menu besides the start API play button. Please improve these. I am definitely looking forward to a second version.

Pretty boring. A proper game should at least have a real goal, shooting 25 ducks and choosing if you want to retry doesn't count.

Playing this game will ruin your mouse.
