I'm going to act on a "temptation" here. But not necessarily the "good" kind and give my opinion on the concept surrounding the main threat, the "succubi" of this game. I think this concept of a succubus is very interesting, but will also say that I do not see them, in a literary and technical sense, as succubi. I have read from the dev somewhere that they are more like life sucking parasites. I only state that I am aware of this because the title of this game, to me, is misleading. And as much the dev said these are not monster girls, I somewhat find them as such ironically, because they kill you unforgivingly and viciously. Lore, story, and world building is really what drives me to games and I feel really compelled to say my opinion on this aspect of the game...and that is the story is wonderful with world building that is not even slightly attempted by most porn games on the market. Which unfortunately, I have to shy away from this game itself, despite extensively reading up on said lore, due to one simple and incredibly frustrating aspect of the lore...you die from having sex with them. My reasoning is below.
TL;DR: Because you die from a sexual encounter with a parasite, I find it a sexual turn off, and thusly, find no reason to really enjoy the sex scene itself. It feels more like one-off, non-canonical fap material. I'm more of a fan of setup and world building, so this isn't my cup of tea. It is because of this I do not feel they are true succubi, but to the devs credit, was the point and they are more like parasites. I find it incredibly frustrating you cannot at least survive an encounter with even one of them and I really REALLY wish this concept didn't exist in the lore, as the concept of them, other than the fact you die from them, is incredibly interesting and a turn on. But this is your game, you make the rules, and I'm not gonna be that guy that tries to force it to change. I just wanted to share my frustration on this. I don't necessarily "hate" the game or lore in anyway and I want that to be made clear. Having distaste for something, and becoming a hater of something is two completely different things. If it came off more in the "hater" way, I sincerely apologize. I did not judge my opinion based off of gameplay, but only off the lore. I may attempt to try out the game to see how it goes, though.
