I like the art and idea. If you want to continue building this, I would suggest making small bums in the level walkable and not requiring a jump. Also, the beginning of of the level teaches the player that blind falls just have more level, but on the low route, when you keep going, you just fall off and die, with no indication it's a cliff to nowhere. Also further meet the theme you could shoot the sword into walls to create a platform and have the main character strong with the sword and very weak while it's gone. Overall great job for a game jam. Keep making games!
