This is a really awesome concept! I've always been a sucker for throwing weapons and cool dashes in games, so this combines those to great effect. I agree with the other commenters, it's pretty difficult past the first level and some sort of aiming indicator for the ball. I also noticed a few times in the second level where it felt like I dashed through an enemy but didn't kill it. You could definitely make this into a fully developed game, I would 100% play it!
