Great work!
Really enjoyed playing the game. I liked that you got the bad ducks that you "Killed" as new ducks in your little hoard. For the few wind up games I have played so far I think this was the best implementation where I didnt feel too overwhelmed having to re-wind everything back up.
Feedback; I had a couple of times where a bad duck would sit and attack my poor clock and my ducks wouldnt go attack them. The last feedback would be the health bar UIs in the game, currently they will overlap my character which felt a bit weird to me. Perhaps sorting them based on the main element (Character or duck)'s y position.
