Absolutely stunning graphics, this is an impressive use of shaders. Very artistic.
I like a lot of the flavour of talking to and helping the other animals along the way, it really brings the theme together.
I ended up doing two laps of the river though because I did not realize I needed to honk to open the gate at the end, I had thought I just missed one of my kids.
Which brings up my only real criticism of the game albeit small, which is the background song can get a little repetitive, but I probably played the game way longer than I was supposed to.
Great work.
