It was a lot of fun controlling the horse, this is the kind of game that I would have spent hours playing when I was younger. The animations were fantastic, the music fit well.
Like some of the other commentors, I had a hard time knowing what I was supposed to do. Maybe having a guide path on the first level so players can get a visual idea of where they're supposed to go could be helpful?
Overall this was a really solid game and the controls felt great.
