I wasn't really sure how to use the second ability, so I wasn't able to finish it. When i used it i got launched off the side and got teleported back to the start. I thought the jump orbs were a cool idea though and it made navigation quite a bit more interesting than the platforming on its own.
For the player character, I'd look into increasing the gravity scale when jumping, and increasing the amount of air control. If you were using Unreal's CharacterMovement component, both of those should be sliders you can play with.
The music was really nice and I liked the floating island vibe, but I think a little more work on the technical aspect of the game would do a lot to help.
