Needs a feature added or two...

From what i've seen this is not such of a good game (I've rated it 2). It needs a save feature and needs to be more dark and mysterious. What i'm trying to say is that it would be better if you remade the game. Some of the difficulty ratings on some of the levels are inaccurate (For example, lungs are rated easy. I would rate that one normal). I am expecting the sequel to be way better than this,

Nice but too hard

i just dont find games fun unless its spoonfed to me, and then maybe some hard levels...

Like Paukl said

Nice idea, but even on the 'easy' liver there are too many obstructions so the enemy particles quickly gang up and close in on you. The game definitely has potential though :)

Nice idea

Unfortunately, it's not really playable. It's not really possible to outrun the white bloodcells so it just becomes a matter of luck whether you make it or not... too bad!

Interesting take...

Seen many virus games, but I like the way you did this one. I would probably up the difficulty on the liver, though, because it isn't "easy" like the lungs. Also, I would probably just have the virus follow the mouse cursor without holding down the button, because the clicking can be a bit buggy at times (at least for me).
