Nice game. I gave it a review and a comment.

Both collaborating & racing at the same time was a really clever twist on the theme, and made for great gameplay. The only criticism I have is that it was really hard to get used to using W for jumping, maybe interacting with the other horsie could have been a different key? And I think it would make more sense for the speech text to write out faster. Regardless, it was a really fun and clever game!
