This was a really fun entry to see, very interesting interpretation of the theme. I though that the gameplay needed a little bit of tuning because it was easy to win even without playing. Maybe for this version the win condition could be more then just one animal, like 1 of each species at least. I felt it fun to try balancing the food and animals, and this could be a really great mechanic if balanced a little bit.
There were some confusing sounds going on, with so many objects moving around it can help to focus the audio design on just what the player is doing.
