I really enjoyed this, it was really satisfying having all your shots go off together to accomplish something especially with that punchy audio. My only criticism is that on some levels, like the last, it was possible to create a mess for yourself that wasn't easy to fix (sending the elevator too quickly, shooting near your spawn, etc) and there didn't seem to be a way to reset the level. It didn't stop me from beating the game but it did force me to sit and wait for the bad copies to finish. Other than that, great submission!
