I think it's a decent game regardless of the lewds. I had fun playing thru it a few times to get a perfect run down.
Also she is VERY hot, some of the lewds are pretty nice. I'm actually not into the murder endings in THAT way, those don't mash well when I'm looking for the lewd stuff. However I do think that the existence of it in this game and the way it's handled does give it a unique and great flare. It feels more realistic in it's dark fantasy way, and the existence of death kinda makes the lewds better too...in a twisted way. Because not everything wants to fuck her, but instead just kill or eat her, it does make it so that the things that do wanna fuck her, actually wanna do it, it makes the rape all the more real cause in this world, it's not the only option, which means it was the chosen option, while in a normal hentai, it's just the only thing that can happen, feels more plot armorie when nothing can harm the girl, they just bang her and then she gets out of it and keeps going like nothing happened.
I'm into dark fantasy so this game does give an interesting mix of that and hentai at the same time.
