I made it to the third level! I like the idea,  but it gets complicated very fast, I would make it a little more friendly at the beginning, that way you can get used to coordinate and don't feel frustrated. Very cool idea again =)

Cool concept, but I wish the ball conserved momentum better as i struggled to complete even the first level. With time and more polish i trust it would be an amazing game. Very Cool =)

Like other in the comments, I wasn't able to finish even the first level. As I can see you developed on Unity, I think with a few tweaks with RigidBody (gravity and forces) you can achieve something way more interesting.

Also, when you change control it is frustrating to press again spacebar. What I mean by that is, it will be better and less frustrating to hold spacebar and change command based on your inputs. Neat concept and don't remember to test with care your game, even if you are not good with testing, ask your friends to do it or just play it for a few minutes.

Cure art!
Original and entertaining concept.

The concept was alright, but it was really difficult to play when your character doesn't save momentum from moving. If you could build up speed when you move, and then switch to a jump, it would make it much smoother to control, and much better feeling to play.

Sadly, I didn’t manage to finish even one level.

I think you had a good concept, but it needs a lot of tweaking. As others said, the control scheme wasn't the best in this situation and a bit more physics would have helped against most challenges.

The level design was also a bit too intense, maybe it would have helped with smaller challenges in the first 2-3 level. 

Nice attempt! I liked the way you have interpreted the theme :) 

 the control scheme  is not good, i think it's just frustrating. There is not much else
