Very well done! I especially enjoyed the music and sfx :D The controls are nice and responsive, I did not see your comment beforehand though so I did not know I could shoot until I got the rule "You can't shoot" I died immediatly and proceeded to press all the buttons :P
One tip/suggestion for the future would be to shrink the enemy hitboxes a little bit. I died quite a few times where I did not feel like they had actually touched me. I find its best to have hitboxes be in the players favour, to not leave them with that frustrating feeling of having died without it "being their fault".
