UPDATE: The half-screen issue has been fixed. It was a problem with Firefox rendering CSS differently than Webkit. Sorry for the confusion!

aren't white blood cells supposed to kill the germs, instead of the other way?

I usually review stuff and not just comment but this game will not load on me!my flash is current and I am currently using internet explorer

Nutcasenightmare responds:

It's not Flash, it's HTML5 - which Internet Explorer has very poor support for. Try Chrome or Firefox, which, frankly, are better browsers anyway.

Ok now i need to admit i probably can't code a game like this but shouldn't design be this bad? It's simple and that is good but its designed to be annoying and much like arcade games of mid 80s it is really annoying to control and lacks too much content after 10 minutes the game runs out of things to throw at you 2 stars 1 for simplicity 0.5 for presentation 1 for being obvious starting work

Pretty original...I guess, nice title. However, this game is REALLY annoying to control, as I have to click the opposite direction, and even then, it doesn't go exactly that way. The game was really repetitive (should add upgrade grabs and viruses for the white blood cells to destroy. Eventually, I have a shitload of cells spread far apart, so the screen zooms out so far I can barely see, and then there's lag. And since these things are stupidly hard to control, I can't group them back to together. I have to say, this is rather professionally made, but the game itself just isn't that good.

I think this is awesome, but am I the only one who can gain points nonstop by going backwards and around the vein and just keep gaining points without running into clots, aimlessly floating through the body? That's the only reason I took away a half star. Otherwise great job. Oh and if I have a ridiculously high score its gonna be because of the glitch.
