The animals are very beautiful, you can see the quality of your programming, and they behave and work very properly. I love it
Suggestions: Since you have put symbols "???" I will take the liberty of giving you ideas that occur to me, you are the developer so there you know haha, mobs in the dark and for caves, not necessarily spiders or bats or the classic, although welcome, but also serpietes, species of insects and then that they have their respective neutrality or hostility, and fish, I know that there are already others that have made fish mobs but I would like to appreciate your quality haha. Best regards.
