I liked it, nice concept, one of the few games I didn't want to reach for the mute button, I didn't even notice if there was one...
to the guy who said "HIV isn't a disease.... it's a virus (Human Immunodeficiency Virus)" Influenza is a virus, measles is a virus, hepatitis is a virus, herpes is a virus, smallpox is a virus, and yes HIV is a virus which adds to the continutiy of the game in that you play as a virus, a virus of each different virus.
