The gameplay was severely hurt by the fact that you used A (traditional left key) for up and D (traditional right key) for down when in most cases we would use W for up and S for down. I solved it by rotating my keyboard... but then the spacing on the keys felt off. Also I think there was a bug where the control swap didn't swap controls.
Otherwise, the idea was there, the game played pretty decently, the visuals and audio fit pretty well, and the theme is met.
