As a whole, this feels like it could have just been a mario maker or super meatboy level. It was frustrating dying a bunch and having to just do everything over again. That being said, you made this yourself, and you did a great job finishing it within the time limit!
I like that the limited uses of the sword give you an option of making the level easier, since you have to loop around the same enemies. I don't think the shield is that useful, since you have to keep that button held down the entire time.
