Every once in a while, my special attack stops working. It goes through the animation, but no damage is dealt. If this could be fixed, it would improve my ability to collect gold significantly (that and a magnet).
Whenever I try to click on anything, my ducks jump in front of what I'm trying to click on. It'd be nicer, I think, if they didn't follow your mouse. Also, for some reason I can't jump on the final stage.
