At first I failed a few times because I thought the game was only about horses being real, so I put the camels and llamas etc. in the not real category. After that I figured it out and had a lot of fun with it! I also really like the changing sorting requirements! The sorting itself was a bit wonky at times, sometimes an animal would get stuck on the bar or even glitch trough to the other (wrong) side.
The art on the animals is really nice, and the encyclopedia is a fun feature :)
