Wow this looked and sounded amazing! You really managed to create an atmosphere with this, and I loved the different animals.
There were tons of small details like the plants swaying, water drops underground, different footsteps, idle animation, and the player water effects.
I loved the art and colour palette which were really unique.
There was some confused dialog, e.g. when I was the chicken there were some mushrooms that would give fox dialog when interacted with.
Movement could have been a little tighter maybe - it did feel a little floaty and unnatural with the fox, and hitboxes and movement around corners with the fish could be awkward.
Also pressing enter during dialog should first complete the current line so it can be read before skipping to the next one.
