I rarely play games this early but I was curious about the game after reading the OP, and after playing through 3 or 4 different paths, I have to say I wasn't a fan. It's kind of hard to stay interested in a story when everyone is so... unlikable. Seems like most of the characters, including the MC, do, or have done, terrible things and none of them show much remorse or feelings about doing these things. It comes off as being bleak and dark for the sake of being bleak and dark, with a cast of shallow psychopaths.
I'm not very picky when it comes to realism, but the amount of things the MC and his stepsister, who aren't particularly imposing, get way with without facing any kind of repercussion whatsoever is kind of ridiculous. Even if I already knew it from reading the overview, it was still pretty disappointing that the MC isn't blood-related with Lily because it makes the
incestuous sexual tension between them a lot less interesting when she's adopted.
Another thing I wasn't particularly fond of were the sex scenes, I know most of them aren't complete but even those without an unfinished warning felt very underwhelming to me. The scenes didn't really do a good job of building up to the actual sex, the scenes were also very short and they also pretty much always used an angle that didn't show any penetration, just 2 3D models humping each other from the side.
I didn't want to write this as a review since this feels very much like an early WIP that probably has a lot of stuff that's subject to change, and I hate how this site doesn't have a minimum amount of reviews before showing an overall score. I'll probably check back later to see how it progresses. Maybe it will turn into something I like with more updates or maybe it's simply a game that's not for me.
For those wondering about the rape tag:
