Glad to hear that you liked it! I tried to make the game so that it teaches the players something :).
The feline family undoubtedly took first place, cats are cool, both big and small, you just have to be a little faster with the big ones :D.
Actually I wanted to add many more categories and you won't believe it, I actually planned a second category - fish :). Also planned was a category of secular animals and further down the list. I plan to add at least one or two more categories in the future, where fish will definitely be ;).
Well, if there is an opportunity and people are willing, then add more and more content :).
