Really cool, mental video! I really liked it. However, the reason it's only 3 stars is due to the audio quality. It really takes away from the whole experience. It also sounds like it's being played out of some cheap speakers, and for the experience that I *think* you're trying to portray, some rumbling low ends and sub bass would go a really long ways.
Also the vomiting sound effects could be a tad more realistic, and like was said in another review, the vomiting lasts a bit too long as well.
Other than that, great job!
