While I appreciate your feedback, I find I have to disagree that 99% of players prefer sexually explicit material, given the number of otome games that don't have any erotic elements at all.
My intention was never to create a pornographic game. At first, the only character who had any sex scenes at all was Dyson (being an incubus, and all), but I was worried that there would be players who wouldn't be interested in that sort of thing, so I programmed in the ability to bypass the explicit material. After that, it seemed silly to have an entire feature that only effected one of the routes, so the others were given sex scenes as well. From this, you might intuit that the adult content was an afterthought, and you would be right.
As for its "softness", I suppose that's a matter of taste. I wasn't (and still am not) interested in drawing sexually explicit CGs, so this is as raunchy as it gets for my games, and I doubt any of my future games will have even this much sexual content, as I found it somewhat tiresome to write.
For the people that do/did find this game unsatisfactory in that regard, I might direct them to the "erotic" tag (which is a tag that I chose not to apply to my game for this exact reason).
That said, thank you for your kind words regarding the story. I genuinely do appreciate any and all comments, as I know that writing them takes time out of peoples' schedules. I hope that you find other games to your liking in the future, but I doubt they will be any of mine.
