Some problems I had:
- The mouse is extremely sensitive - I find it quite difficult to play in browser, and fullscreen is nearly unplayable :(
- I somehow managed to get negative HP without dying :P from this point, I could freely roam around, getting more damage without any consequence, and also shooting the enemies didn't cause them any damage (I assume that I was considered "dead" due to the negative HP?)
- I don't get the theme interpretation :/
Other than that, it is quite impressive given that you only had 2 days to pull it through. Keep it up!
