Cool game, nice mechanics and also nicely recreated desktop visuals.
I have a couple of suggestions to improve the game if you plan on doing it:
- Add a way to see your current mission again, for example add a "notes.txt" file on the desktop with your current mission;
- Add the possibility to change the z-layer of the opened windows to show the last focused window on top (in Unity, you can easily use "sorting groups" to change the z-layer of all sprites that are children of the sorting group at once, so that's an easy fix);
- Make it clear when you can write on the CMD console and when you can't (sometimes, for example at the start of the game, it won't let you type anything in there, but you never know why you can't, so maybe explain it first).
Nice game concept overall, it reminds me of "Hacknet", good job on the game :)
