I have to say that gor the most part this games is great. The cast is fairly large and varried and I have a soft spot for mind control/hypnotic suggestion so I'm already predisposed to liking this.
That said I do think there are a dew minor things that need to be qorked on. For example I'm a huge fan of Netori or reverse NTR so I really liked the Kristina's obedience substory, but after you complete it she still talks about Kanto as if he was her boyfriend even if you stole him. It would be nice if the dialogue during sex scenes changed depending your story progression with them. Without this a lot of the game feels disjointed and unpolished. I admittedly don't know how much work it would take to add this dialogue in, though.
On a different not, as I already said, I'm pretty big of reverse NTR but so far the only story that really satisfys the itch is Kristina's despite their being multiple married women in the game. I want to ruin marriages. Or alter their husband's minds to the point where they can only get off by watching their wives get screwed. I'd like to see an extension to Yastsumis storyline when, after screwing with Dr.Hiro's mind she comes crawling back to you because he can't satisfy her. All this ultimately culminating with the player character screwing his wife, both his daughters, and his mistress in front of him while he jerks if the floor in tears because you reprogrammed his sex drive so he can't get off any other way. Plus, I'm bot big on Shari g and Yatsumo is probably my favorite of the girls in the game so I kind of want to screw that guy over in particular.
Not just Dr. Hiro either. I'd like to see some kind of similar story involving Utako as well. Maybe film sex tapes with her face blurred out or off camera. Slowly revealing more and more distinguishing details about her so that he's forced to slowly grapple with the fact that his wife is sleeping with another man. But just like Utako his parents also pushed him into this marriage, and revealing the tapes would be too shameful, so he can't leave her and is forced to get his sexual gratification watching those tapes when he's home alone. Even better if you could have him forced to raise the player characters child if you get the pregnancy ending on this route.
Hell, I'd like to be able to screw Kanda over even more by having an alternate Atsuko path if you've already stolen his girlfriend where both the character and Kristina seduce Atsuko to the point to where you can screw them both in front of him before she kicks him out of the house or something.
I think you get my point by now. I love that you gave a lot of the girls their own families, friends, and coworkers that overlap with each other. It makes the game feel surprisingly lived in. But I feel like it also creates a lot of opportunities that could be expanded on.
All of this is just a suggestion based off my own taste, though. Except for the suggestion on dialogue changing as you progress through obedience stages and events. I think that's a key fix that needs to be made. Great game, though.
