A solid submission that fit the theme well, congratulations.
My biggest criticism would be that the boosts were extremely difficult to use. I understand that they are one of the key skill gates of the game, but they were frustrating to work with at times. I think this is why in Ori & The Blind Forest, the equivalent mechanic allows you to aim where you're going and fires you at a fixed velocity, so that the handling is predictable and precise without sacrificing player skill. I wonder if that approach would work better here?
Best of luck with the ratings and happy jamming!
