I enjoy the idea being presented but it is HARD. I tried hitting the targets in the tutorial and the first set of levels but it was almost impossible for me. Even when I'm just hopping around it is so easy for me to get myself killed. I think most of the issue for me was how fast the jumping charge filled up. I wasn't able to always get the right amount of force.
I could see some good players pulling off crazy stunts with these mechanics once it is refined.
