Controlling a computer inside a game you're controlling on your computer is always a concept that piques my interest and I appreciate more games like this. The interface reminds me a bit of my days as a kid when I figured out how to change the design, colors and fonts of Windows XP. Given that GHOST OS was built by a young hobby developer and never really finished, I can see how she would do similar stuff with her project and I think you conveyed that aspect pretty well.

The soundtrack is pretty cool and having to find the files before you play them is both realistic and a good motivation to look for secrets. Having them also play when clicked on instead of just being added to/removed from the playlist would be a nice addition. A few more system sounds for opening files, warning messages etc. could improve the immersion even further. The fan noises and the whine when you shut down the computer are a nice touch, though I only noticed them when I switched to headphones.

I have to admit I didn't get very far. I've read all the help documents and interacted with everything I could find on the guest account, but I probably missed something that would have helped me finde a code to create a real account. Opening folders also confused me a bit in the beginning. I thought clicking on any of the rounded rectangles would open the folders, even when you're hovering over one of the icons. For example, clicking on the news icon in the program overview would show a message about insufficient authorization which lead me to believe that the whole folder was unavailable. I was pretty surprised when clicking a few pixels next to it one or two minutes later later would open the folder or the help file. The selected icon gets a bit bigger when hovering over it, but maybe the highlighting could be a bit more obvious? Then again, it could just be me.

Nevertheless an interesting entry and take on the cartridge!
