Thanks :)
I agree that waking up and putting ducks to sleep is sometimes hard to manage. I was debating whether or not I should make a third button, as it would make things much easier. I wanted the game to use as few buttons as possible (ideally two, because there are two buttons on mouse), that's why I had it that way.
Thanks for sharing this, I will seriously reconsider the third button. It seems that a lot of people think like you, so I will likely go with it.
