Thanks for your feedback dude!
I'm glad you asked this question!
Actually I was going to work on one more mechanics in which you can climb the wall using your sword!
But my game engine crashed few hours before the jam submission so the level I made was gone 😔
Try this...
Go towards extreme right wall and stick to it!
Now keep right arrow pressed and try moving your mouse clockwise such that the sword moves in a circle, you will climb the wall!
I hope you get it! 😁
