Pretty interesting idea for the game! I did feel like the stats were a bit confusing as while everything was red or green I couldn't really tell which of the attributes affected which stats the most, which I'd have to test by changing the stats themselves, only to forget by the next time I make new critters. Some kind of label would also feel useful on the different types of critters themselves. Otherwise I really liked the music and art and felt like it was really coherent together with a few minor polish tweaks I could see something like this doing pretty well outside the jam.
