I was confused and thought the knight is our player char but then I realised it's the enemy and we are in first person. :D
I love the art design! The enemy looks and movement are great. Subtle animations in the background would be a nice addition, like subtle movements in the clouds or very slow falling snow. The "risk it for more" is missing somehow. I also missed more visiual feedback if the plyer gets hit, maybe red color or blood on the screen?
The music was music superb, though no original composition for the game. Gameplay was fun and challenging,
