Hi! Welcome to the system. Today's mission is getting into the firewall as viruses. We have 401, 402, 403, 404, and finally firewall as walls. You can switch your character by tapping on the left of your screen. When you are copycat, you jump when you touch the right of the screen. When you are rat you go fast when you touch the right of the screen. When you are worm you duck when you hold the right of the screen. Good luck!
