The following review is based off my personal experience with playing this Game/Visual Novel... I try to be as brutally honest and detailed as I can, and these are my own opinions and thoughts, from one or more play throughs... The version this review is based on is A5...
Not much content once the grind game begins, but it's an interesting introduction...
What little visuals there are, not all of them properly size correctly to the screen (I used Chrome)... The visuals that do exist are primarily black and white 2D hand drawn pictures, but even then they look very well made... Can't wait to see how that aspect evolves...
The script does have the occasional spelling/grammar error, but nothing too bad... The plot revolves around a male protagonist who just inherited his great uncles home, money, and 2 slave women (they are labeled as slave girls in the text, but technically they are women)... Both of the women are sisters, with the oldest being very protective of her younger sister... Both had been poorly treated and subject to chemical enhancements, with the oldest being extremely mistreated by the uncle... The uncle apparently liked to play mind games, sexual assault, and torture his slaves... And before the protagonist arrives apparently there were originally many more slaves, who were taken away by some mysterious slave trader...
In any case, the protagonist has several ways in-which he can treat the two women, to include being just as sadistic and controlling as his uncle was, or by treating them with kindness/respect, and possibly other things as time goes on... As once the introduction story is done, a grind game begins... All you can really do for the moment in the grind, is move around inside the house, with a few interactions available with the oldest woman (Anna)... You can also engage in sex with Anna, and change a few settings for Anna and her sister Eve, such as their sleeping and eating arrangements... There really is not much to really do beyond that, for the moment... So the playable grind content is extremely limited...
Overall, I'm not a fan of the mistreatment portion of the game play, so I opted to go with trying to reverse the damage and maybe go down a more love/romance path... But for the moment the content is so limited, there are actually more harmful interactions available then good interactions... There are random moments where you can interact with Anna while she is attending the home's cleaning, but they are repetitive and don't really seem to do anything at all... As when you have a casual conversation with Anna, her reply is always the same, no matter how many dozens of times I helped her during random encounters...
How far the author's plan to go with the depraved portion of the game, I don't know and probably don't want to know... But I am looking forward to the love/romance and fixing them, aspect... The game does show some potential, but only time will tell... This game is very early in it's production, so it will be a while before we start seeing a bunch of content for the grind game... I'll most likely revisit it, once it gets a bunch more content patches under it's belt...
