The game worked for me! I played it through and I must say, for a 2 day project I am really fond of the fact, that you added sound into this game!
I took some time for the game to finish, cause when it said "0 Enemies to kill", I could still kill some for like 5 seconds or so.
The game play feels really repetitive really quickly. But for a project with a dev-time of 2 days, you cannot ask for too much.
I played this game on a Firefox Browser.
