We have actually 12-13 levels!
Probally there is something for you to change in the rules of the game haha
There's a hint in the game, if you double click on some of the icons you can see interaction with the files of the computer!
(Specially in the level 5, you can find a hidden folder, if you open it up there's something for you, the most part of the folders/icons of the desktop are interactable
