It's SO MUCH FUN!!! It's also really informative and includes information about the genetics!!! The directions on how to use it are at the top of the screen, although, if you're like me and rarely read directions when it comes to games, it's kinda hard to figure out on your own. The little square on the upper right corner contains information on all the different genes, and my horse geek brain is literally FREAKING OUT over how cool this is XD It's kinda wonky with saving it, but here's what it looks like:
