Nice take on the theme! I liked the art and animations. I had fun, although I couldn't get past the second round.
I did find a couple of bugs. First, you can pick multiple ducks in a single round. Second, after picking a duck, you may exit the main room, re-enter it before the door closes, and then touch the bottom door. This will allow you to skip the entire course and end the round almost immediately.
Great work!
