Reviewed at v1.0
The [Completed] tag is flagrant false advertising in the latest in this series of morally grey decision-making games. Third in the series, this game offers the least of all of them. The game is remarkably brief, and almost impossible to fail. The decisions are largely meaningless -- there are obvious right and wrong answers, and if you save before each decision you'll be able to get them all right all the time.
There are less characters than HnS2, and they are all much more shallow. The sexual content and setups is equivalently shallow, leading up to a small handful of linear, guaranteed scenes. The artwork in those scenes is of better quality than the previous iterations, but the minigames layed over top of them are a nuisance. Half the time you're getting treated to the reward you were working to earn, you have to waggle your mouse like you've just checked into a severe palsy ward just to keep the girl "excited" while you flap your dickskinners around her motionless breasts.
Worst of all, the game explicitly states that certain content won't be available until "later versions," but describes itself as v1.0 and complete. The only redeeming quality was that the art was a little bit better, and adequate for your session, but otherwise not at all a worthwhile experience.
Pick something else. If you're intrigued by the concept, try Hack'n Stalk 2.
