How to Play?

How good are you in drawing circles using the mouse? Very good? How about drawing circles using the mouse, FAST? Still confident that you can do it well? Let's prove it in this game, shall we? Your job is to protect the heart from the attack of viruses; to do this you have to draw circles around two or more viruses of the same type in order to eliminate them; note that if not all viruses in your circle are of the same type, none of them will be eliminated. You don't have to worry about drawing actual shape of circle though, all that matters is that you actually encircle them within your drawing. The path that you draw is fool proof so you can use it to protect your heart from being hit by the virus. There are two modes of play that you can choose: the Bring It mode will deliver the onslaught of 30 waves of viruses; see if you can eliminate them all. The multiply mode will allow viruses to multiply without limit, so it is basically a test of endurance, how long will it be before you are no longer able to eliminate all those viruses and have to give up the heart?
