Nice game!
I really liked the duck character and its animations and I think the platforming and level design is well made.
I had some difficulties with the jumping and also I ended up stuck in a corner because of a crow. I think it would be cool if you were able to have the gun rotated towards the mouse or some way of shooting the other direction. Also a small thing would be to have the bread pickups as triggers instead of colliders, because right now it stoped you movement, this is a small thing but overall nice job :D
