Use the arrow keys to move the white blood cell. To stop germs just touch them, but to kill them and earn points, press the space bar while touching the germ. Don't cross the red line that the germs are behind or you will lose points. killing a germ is 5 points. when a germ gets to the other side, you lose 5 points. HAVE FUN!!! :)
