Ho-ly, I actually passed most of it. DANG, did it feel satisfying!
But you should be more generous to the players.
Without perfect input and a lot of trial and error, this game is brutal.
I think even too brutal, because it often felt like I have no control.
But still, this is neat :o
You should play around with jsfxr, it generates bleep bloopy sounds with no trouble. Look it up!
Keep on fighting,
