Thank you! The art side of things is definitely not my best aspect, but I am getting better.
The controls for sleeping and waking them up was difficult for me to figure out because I wanted the game to use as few buttons as possible (ideally 2, because there are two buttons on a mouse). I originally had it so each individual duck switches between awake and asleep, but that got annoying because usually they were in clusters so you would just have a few awake and a few asleep. I changed it so that it changes all at once: if there is at least one duck that is awake near you, they all go to sleep. That's how it works. But yes, I do agree that it feels awkward and annoying at times. I will think of solutions.
