Root

Hello, welcome to the operating system, you have been granted super administrator privileges. From now on, you are called "Root" and your task is to remove viruses and bugs from your computer and bring it back to health. (Hint: If you fail, you will be shut down with this computer.)

Your goal is to find the super virus (boss) that will crash the system and destroy the boss. You can acquire skills and batteries (hit points) by exploring the different folders (rooms) in the system.
