The visual, sounds and the game idea of more ducks is less courage is really nice.
It was quite annoying to control the character (especially wall jumping). I get, that the more ducks there are the more difficult is to control the character, but even with 0 or 1 duck the controls didn't appeal to me.
Aside from the controls, pretty good job with the game :)
PS: also the game window was super big for my monitor :/
