I liked this. One thing I could say is I noticed a clipping with the duck's turning, this is only a game jam version and as well it doesn't hinder game progress so I'd say don't worry about it too much.
One thing I loved was the option to go into first person and that feature kinda gave me Baba Is You vibes.
All in all, this game is really fun and I can't really say there way anything left out of the puzzle game atmosphere!
