Amazing entry. Very innovative, excellent gameplay, nice puzzle design, good audio and artwork. Fantastic work!
My only criticism would be the reset animation takes way too long. I’d have it very quickly transition back into the action.
If you consider furthering this into a full game (it’s definitely worth considering) I think the physics could use some final layer of polish. There’s often times when the water unexpectedly pulls the duck backwards (my guess is there’s a single pixel moving back upstream which pulls the duck, but visually it looks like it’s going counter to the motion of the ocean) for example… basically some extra polish would really make the puzzles extremely consistent and push the quality level up to 11.
Great work across the board, very impressive!
