Honestly, I wanted to like this game. I really did. The raving 4 to 5 star reviews - of which there are plenty - I do believe are justified. But, for me personally, this game fell a bit short in a couple aspects.
This game is good. Let's get that out of the way first. Here are my gripes with the game, that clash quite heavily with my tastes, and as such makes me lower the score:
The sex scenes are in a different "map" and are very "self-contained". Sex that actually affects the story or happens "naturally" or you can seek out as a "story event" are few and far between and most of the sex comes from looking for items (called kamasutra pages that enable a sex position) that will then allow you to see that sex scene in a self-contained, sandbox style room far removed from the actual plot of the game. Jealousy between the characters and other plot points feel moot because the actual sex is so far removed from the game that it feels jarring.
The puzzles tend to err on the side of boredom after some time, and the tedious amount of walking in the ever-expanding map is sure to get on your nerves, even after the teleporters are activated. Not only that, but while the story is good, the gameplay is not. There is close to none incentive to talk to all characters all the time because their dialogue is boring and short if they're not in the current part of the plot, nevermind repetitive. This, paired with the premise of the plot is you locked into this university, makes the entire game feel thoroughly repetitive, especially since the characters very rarely move into the areas that you open as you progress.
These two things made me lower the score a lot, particularly the sandbox-style of sex scenes. Nonetheless the story in this is quite good, the renders are - as you can see - exceptional, and the game is complete and the sex scenes that do exist within the story are nice; unfortunately, the "bulk" of the actual H part of this game is so thoroughly unenjoyable to me because of the sandbox aspect that I cannot give a higher score to this.
If at any point in this review you thought "well fuck I don't mind this at all", then do play this; you'll probably give it a 5.
