There are parts of this that look super polished, especially given the jam timeframe. I enjoyed collecting the creatures and unlocking all the abilities. It quickly became extremely easy to complete runs, even when swapping in a couple new level 1 creatures to see their abilities.
It took me a while to get a Deer to hatch, and in that time I collected so many eggs... because you can only hatch one egg per run but find multiple eggs per run, the eggs pile up. By the time I got a deer I had enough animals that the UI for picking your team had animals off the screen so I couldn't select them anymore.
Given the visual polish, I felt the lack of sound extra deeply. I didn't understand what the animal icons on the left during battle was supposed to be until I read the comments and saw it's the initiative order.
I liked the drag and drop mechanic for the abilities, it felt very smooth.
