First things first... incredible aesthetics and presentation. The visual design and audio are all top notch. The voice acting is excellent and really adds to the game. Gameplay-wise, there's a good variety of abilities to use that keep it entertaining to play.
That said, the actual control and game-feel is a little off right now. The platforming itself is solid, if a little stiff. Attacks don't feel as satisfying as I'd like, and it's a little tough to get into position to deliver them. The end boss was really hard, and it didn't feel terribly fair. I'd say that each of the boss attacks need slightly more "tell" time to help the player get out of the way. The projectile attack was fine, but the biggest offender in my opinion were the random strikes that could hit you anywhere. If i wasn't already running and jumping non-stop, there was almost no dodging those.
I hope you'll keep working on this project, despite my gameplay issues, I did see it all the way through, and beat the boss after many attempts XD. I think you've got something really special here, and with some refinement will take it to the next level!
