Sorry about that. I've been having this problem here as well. I thought it was something with the itch servers so I've waited a few days, but clearly isn't. I'l keep looking for a fix.
The art was amazing. Simple and elegant. The idea for the game was also quite good and the implementation was almost flawless. My only problem was the speed in which I had to place the jumps before the horse killed it self. This gave a nice twist and a sense of urgency.
