This is a satisfying game for fans of the voyeur genre, and a must play, I would say, and I will explain why you should check it out.
First of all, the characters are all good and well done, the grahics are good too. But I would say these are not the selling points of this game.
I should advise you that there is NTR in this game, so if you are a fan of the genre this game is a must, and even if you don't mind the tag this game is a voyeur godlike (I will explain why soon), so only if you are against NTR I would not recommend the game for you.
Ok, so now I would like to tell you why this is the best voyeur game I have seen. So, this game plays around a lot with the voyeur mindset, the game puts the characters in situations where you think "ah, it would be nice if X fucks Y" or "it seems that A is flirting with B, or am I wrong?", if I do this "X will fuck B?" and as the game suggests these thoughts in your mind, it also rewards you proving that all your assumptions were true. So, as perverted as you are, what you expect, or would like to see is usually provided, and you can influence on it happening or not.
For me, the act of me thinking it beforehand, as a "ah, that would be nice", and be rewarded of my voyeurism ideas happening again and again is priceless. And the NTR connotations of it is just an icing in the cake.
This review was not as clean as I would like it to be, but I wanted the convey the idea of giving this game a shot, as it expands on the genre voyeurism as I had not seen before.
