white blood cell game

In this game, users must use the arrow keys to navigate the white blood cell through the bloodstream. The main job of the white blood cell is to protect the body from bacteria. In a similar fashion, you must hit all of the bacteria visible in the game. If you do not hit them before they leave the screen, you lose points. Every once in a while an antibody will appear on your screen. If you catch this, you get a bonus 100 points. Try and survive the full time and see how high of a score you can get.
