Hacknet game

It’s $9.99 on Steam and GOG.com (apparently no DRM there).

It is based on real hacking and is quite educational. In the game I had to hack another hacker’s computer and he got revenge. It turns out he removed one of my system files that stopped the GUI from working. I thought something was wrong with the game. But I did an internet search on it and found out how to fix it using just the command line.

This looks kind of intriguing, actually.
