Sorry about the last word in the acronem, i just needed to make it SICK.
Click a non-green square to infect it. All squares EXCEPT the green square(s) can be infected.
To activate the green square (healer or KubeKleenex), click it. Please be patient if the infection stops for a bit.
If it just won't continue, remember, ANY NON-GREEN SQUARE CAN BE INFECTED! just click it.
