Here's my controversial opinion: a game can't ride on visuals alone.
Don't get me wrong, this game is super hot and the graphics are among the best of the best in this genre, at least among games that seek to have a realistic appearance with believable models. Graphically, it's a standout in a class of its own.
The story is where I find it's lacking. First of all, the mom character is an absolute fucking lunatic, no two ways about it. Nothing but completely unrealistic, insane-seeming behavior from this California dime of a super-MILF. She shows disturbingly few qualms with jerking MC's dick for him right from the get-go, even showing up in lingerie and letting him grope her while she beats him off in a very intimate, clearly sexual and non-clinical way the FIRST time she does this. We dive right into H content and there's very little pretense of her being apprehensive about helping with his "condition," which is also deeply contrived and is pretty much just a case of blue balls.
It's lacking one of the things that, for me specifically, make incest-based games enjoyable: a sense of progression, of hesitation to take the next step, of wondering if they've gone too far or trying to continuously normalize their taboo acts as they grow more extreme. There's basically no real acknowledgement of how unspeakably inappropriate their behaviors are as family members, and it's all couched in the early game in this strange routine of her pretending to be another person while she does sexual favors for MC, which makes her seem even more like she's completely out of her mind. Basically all this to say, it severely lacks subtlety or realism of any kind.
Another minus, with a bit less importance, is the lack of choice. Normally this would be more of a pain point for me, because I like having various options for how I can experience a story, but I feel it earns its keep on this front by making all of the content that it contains extremely high-quality and hot, even though you're basically restricted to a single track of moving through the story and there's very little variety available, besides occasionally getting to skip some specific types of content, like feet stuff. People often say a story or game is a mile wide, but an inch deep; this is like the opposite of that. What you get is really solid.
That said, I uninstalled and I don't see myself reinstalling because I've basically seen all of the parts that I enjoy enough to really get off to multiple times, and with no alternative routes to take, I don't see myself needing its assistance again. I got a pretty average amount of enjoyment out of it.
tl;dr - game looks great, hot concept, but subtlety/pacing/realism is poor and variety is almost nonexistent.
