To be clearer then, I like the game, the characters, the writing, the layout, images and the work put into it, but I also found mixed messages in it as well. There are plenty of fetishes like pregnancy, lactation, breastfeeding adults, voyeurism, toilet voyeurism, urination, exhibitionism, domination sleep groping and sleep sex advertised and present. Behavior that most people would think of as "hardcore".
Take the sleeping sex scenes as an example. I doubt that becoming sexually aroused by someone who is unconscious is something anyone brings up on the first date as a "normal" thing they do, therefore it is not just a vanilla game, nor is it advertised as one, but to me it feels like it is.
Like an introduction class to bondage. A sexy, fun experience, but also safe, clean and harmless. A treat for some but not for those that expected more from the advertisement, and got fragments for the masses.
