Hello, I just finished the game so far, and loved it ! However, I don't know if this is a bug, but when I use the keys in appartment 301 in the "Lost Key" quest, it doesn't give me the"quest completed" notification.
Also I couldn't find how to start the "Password Protected" sidequest in Kiel, a little hint is welcome.
In any case , you and your team did a great job on this game !
Keep up the the good work!
