Damn that was stressful, but I won! At first, I thought without a timer on the current command, the game might be too easy but boy was I wrong. It's pretty challenging, and I never even got an out of control virus. It would be could and subtle if you checked what the next required input for the command was with your individual viruses, and if they are close to the key that corresponds they latch to it, because then it makes you more prone to making mistakes since you usually erase the whole string of identical letters in your command after having gotten rid of the virus. Great work!
