Vivirion

Cute, although the mouse control was really jerky. I would have liked the option for keyboard control.

Cute? Really? I think I'd rather have played an antibody. The yay factor of achieving disease is a little distasteful to me.

The Host Is Dead.

Medal Get! HIV +25 points.

Awesome, can't wait until I get to play as a breast tumour or bowel cancer.

As for the actual gameplay, it was boring and repetitive. I don't think the upgrades even did anything.

Far too easy.

The challenge in Fishy was that once you got to level 5 or 6, the game sped up to the point that it would almost always throw some impossible situation at you. Here, the slower pace of the drifting blood cells and their relative sparseness made the game pretty boring.

Not only was this ridiculously easy and boring, and the upgrades utterly pointless, but this game gets how viruses work completely backwards! Viruses are smaller than the cells they infect because that way they can enter those cells and modify their DNA to produce more viruses. This is stuff I know from a high school biology course years ago, for crying out loud. Talk about a fatal research failure.

Echoing Xindaris's point, on the HIV level I kept trying to infect white blood cells on purpose.(Not a precise description of how HIV works, but close enough for this purpose.) Would have been cool if you had to seek out and infect the types of cells that the actual viruses would target.

This game lagged terribly mouse-wise in my case, so after level four I sadly called it quits.
