I didn't finish all the content, I've played until the first curse break and Sera's first training, but I already want to say that's the writing in this game is really among the top, especially among games of adult genre. The thing is, when I read the description I was already intrigued, that's a really interesting not very often seen story setup. To be honest, I was thinking that the "girl" in the second preview picture will be my main goal in the game. As it turned out, the hero
Well, I thought to myself: Maybe the author planned for us some plot twist where everyone in this world was expecting another man-hero, but instead it's just a tomboy in disguise, who trying to meet their expectations? And the truth will be revealed later? Reading the comment's and understanding the true plans for this character I was slightly disappointed, but only slightly. If the dev make true female out of him it would be nice, but if it will be trap, it will be end of the content with this character for me (if it's not optional), since I'm a straight guy. Basically, it's already girl, it's just only during conversations we hear about him as a man, so, it's not a big deal for me.
Maybe it will sound surprising but in my rate the priestess takes the last place of attractiveness, yet, I was really into her. She is very well written character, who has clear motives and interesting view of things. So it was pleasant to read all their conversations with Mars. As for the rest of cast I must say I really see the problem that the relationship with Vi almost not showing in the early stages of the game. We have very caring girl beyond our side and yet, there so little conversations with her, not to mention there is zero sex with her, only mentioning it in dialogues. And if I rate all the cast judging by their look I've seen so far it would be: Erin (thinking as it's girl), Lavinia, Vi, Sera.
Also i wanted to mention the dungeon, which looks quite nice, with all these battle animations and character sprites. It pains me that this part of game simply not serving any purpose now. I hope one day the dev make some interesting game mechanics for it, like some monsters that can rape those already brainwashed girls (if you allow them) or you get some interesting items, artifacts that can give additional options during trainings.
