Nice action platformer! I loved the fact that you even made cut scenes and a boss!
Two things I found a little off was:
1. The control of the knight while he is airborne. I feel like a needed more control and couldn't safely calculate landing on platforms.
2. There was a time when you have to double jump and dash while you are sliding a wall. The first time I got there I had used my double jump and couldn't make it across. (I think the double jump should refresh when you hug a wall)
All in all, great game and excellent presentation! Have a nice game jam!
