The puzzles or missions are tough, almost like someone knows more about hacking than they should, yet sometimes they are too complicated it seems. 
As I mentioned before, for each mission there is more than one solution. Even though you tend to do the same thing in each mission, you can get wrapped up in the mystery of it and forget that you’re repeating yourself. Within each mission there are clues to help you along the way. Yet somehow the first time through, I seemed to miss the majority of them. The one thing I would have liked to see is a copy and paste option or a drop down menu once you have obtained a certain server, as that would cut down on typing the same thing over and over again.
The one thing I noticed, as a family man who has children/grandchildren screaming playing around the house, you can’t save during the mission. You can only save between the missions, granted most missions can be done within an hour, but sometimes it would be nice to save if you have to walk away from the game. The other side to that is, I found that if you did walk away from the middle of a game, you had better remember what you were doing as it could easily affect you. This happened more than once to me.
