Not super big on dirty/old men but I get that it's supposed to show how low they'll stoop as they're corrupted and lust consumes them.
That said, the game was great. Really can't understate how well the music plays with the cliche, but surprisingly interesting story that's really only a backdrop for the lewd scenes. Not sure who did the translation for this, but it's an A+ job from start to finish which is important for getting a feel of all the heroines. Each girl touches on a different type of niche for heroine while keeping the main corruption theme. It's a brilliant idea and it's executed well.
I'm used to Cecile's type (sweet, clean, ojou that makes excuses to lewd) and her scenes were nice--Tina's type is rare(maximum tsundere, jerk with a heart of gold that gets swept away easy and falls in love hard) but I'm definitely a fan of how they did her. Kagura hits a lot of homeruns and this is one of them for sure. When I get a bit more cash I'll throw some the developer's way in support. It's just a good game. If you haven't yet, try this one out. Can't really say much more than that.
