Interesting concept, but not the greatest execution. The jump felt too floaty, the audio was extremely jarring, the controls were awfully placed (dash with left shift? Q? It was a chore to dash using wasd for movement, and when i changed to the arrow keys I had to put my hand in an awkward position, Enter and x for dash, with x for jumping in addition to space bar, would've been a lot better), and the gameplay didn't feel polished at all. When using the blue/purple light the momentum wasn't preserved, instead it was flipped, which made it feel jarring and snappy, instead of a flow of movements we come to expect of games that play with gravity.
If I was to give a suggestion, it would be to polish a lot more the gameplay mechanics, to make it feel smoother and nicer to play. That is the main metric in a game, how well it can be played and how enjoyable it is.
