I really liked the game's concept, but I think that it needs some refinement. For starters, you have to use other things besides colors to indicate zones so that colorblind people can play your game. For the platforming controls consider making the killzones a bit smaller so you don't actually touch them while standing on a platform, adding some coyote time, increasing the gravity after the apex of the jump, and dampening the y movement of the camera when jumping. Finally, without any point of reference, it's hard to know hoe much the platforms move, so in this case backgrounds or other visual indicators are very important-
