Cool setting/concept. I found myself letting go of the charge before it was fully set up and having to start over, maybe decrements instead of resetting to zero?
Few visual communication issues, I wasn't entirely sure what was hostile and what was friendly on screen.
To me it looks like when the player is flying across the screen they're in a sliding position, so maybe having some sort of combo/reward for shooting/traversing the map before the player stands up would add to the experience, and keep players from playing too safe
