For a first game jam game this is really cool to see!
I know you said the known bug was the animals moving randomly but I laughed at all the animals bouncing around out of their pens.
The advance week features reminded me of some old sim games that I used to love to play and was really nice. I'd love to see you add more features, specific animal needs, etc
Some feedback would be it's quite slow to walk around your zoo, especially when it gets larger. I quite liked seeing everything when I was placing a new enclosure so it would be cool to be able to go to this view and see everything at once. Also some (optional?) snapping would be really nice when placing enclosures.
Great job!
