Overall, this is a fascinating experience! The Hacker Evolution series is a serious treat for the geekiest gamers. What makes it unique and positively special is that it's essentially played by in-game console commands! There are no other games I can name that utilize this as a core game mechanic. In fact, I wish Watch_Dogs played less like Grand Theft Auto and more like this.
My only complaint is that there are a number of points within levels that feel like "Guide Dang It!" Either my brain is not up to snuff, or the levels barely give a clue (if at all) on how to complete the objectives (such as figuring out the names of all the servers for each level). Fortunately, it is ridiculously easy to add content and your own levels with provided mod tools. This gets even better, because the main game levels are treated the same way, meaning they can be opened up and used as an answer key or even changed to the players' liking.
The overall scope of the game is small and simple, but it definitely uses that scale to the best measures possible. A 10-dollar price tag may be a bit iffy for some, but if it were for 5 dollars, it's a must-buy!
