There's been a deadly virus outbreak and you're on a mission to destroy the virus using special antidote cells. Trap the viruses within a wall of antidote cells and drain their infectious energy by stopping them from moving about. Remember, the antidote is very precious so dispense wisely! The cure lies with you!

Instructions:

Hold down the LEFT-CLICK on your mouse to build a drop of the antidote. The longer you hold it down, the bigger the drop becomes. Keep an eye on the amount of antidote you have in the syringe (on the right). You only have limited amounts, per level. Don't touch the viruses when creating the antidote bubble. Trap the viruses to kill them!
