Corrupt makes... interesting games. True enough to their name, their works feature heavily on themes of corruption.
This game features one single scene that could be considered sex, and it honestly ain't even that good. There are a few other scenes, but they aren't much. Honestly, to get any degree of sexual satisfaction out of this game, you would have to be a hardcore corruption fetishist. And while I wouldn't say I myself am hardcore, I do have a fair love of it and moral degeneration. And as a fan of erotic literature, the lack of CGs is meh, in my opinion. And the writing in that regard is superb. Corrupt is very good at what they do.
As far as the gameplay goes, it's a little grindy, yes. But only really at the start. Once the girls embrace their corruption, you at least get to see some really interesting interactions between the characters that play with the themes. And its fun gameplay too. Short, quick SRPG battles that I find to be very well executed. The story is pretty decent too. But in the end, both the story and the gameplay are mere vehicals to drive the corruption themes.
TLDR; a corruption fetishists dream, but otherwise only a decent game. Still reccomended. Est. 7 hour playtime.
