Not a bad game at all! The controls are all pretty solid, and I found myself genuinely challenged and interested once I got past the first level.
However, the gameplay was a little bit confusing. I honestly had no idea how the damage system worked, and if I was attacking those floating skull things or not. I also failed to understand what the point of the dash was.
Although I'm not really sure how a person on a horse can walljump I'm glad it's there, otherwise the game would have been impossible.
