okay, but needs improvements
first of all, it needs instructions. make a page explaining the controls, points system in more detail, and what happens when you die.
2nd, maybe change the dying system, because trying all over again everytime can get annoying
3rd, either make a square player or change your hitbox, because starting all over again when there Was No Visible Hit really is annoying.
oh, and the jump box things were weird: you jump faster and faster for like 10 jumps, then restart slowly. and they are a bit too low, so it's hard to reach the next platform.
pretty good for a first game, still. with practice you will definitely get awesome!
last 2 things: no mute button, and infinite fall is not corrected on the sides of the game map, you may want to correct this on the next game
