Good job and congrats on your submission!
I like the feeling of the game, the gameplay loop is simple yet interesting and keeps the player focused. The ambiance is great with the rain. and music
Here's a small feedback/suggestion :
In the map, you have objects with colliders that you can hit with your "weapon" and they seems to have some sort of use but they do nothing except a reaction event (scale up/down + particles?). If you were to update the game it would be interesting to see specific requirements for different animals obtainable from thoses objects near the Ark. For example you would need a fish for the cat, a banana for the monkeys, grass for the lamas etc.
Overall, I love it! For a first game it's very nice.
