Lovely response!
I know I have not had the opportunity to review your work but from what I can tell you're certainly not a bad writer, even though your English is not perfect. I wish I could help you improve it for your sake, if you even care anyway. I can't expect you to send me content to proofread for you though, nor would I ask you to, but I would offer my help if you were receptive. And in return maybe you'd improve my French haha. Anyway Thanks for the thorough and kind responses you've given me, it's always nice to talk to other kind people :)
Perhaps you are correct about the dark themes being a popular niche, at least in some places. I can't deny that I, too, have played eroge games with dark themes but I wasn't playing for that reason, and I'm surprised that even some of those were made so much better than some games without the dark themes! This is what upsets me most. I guess in Japan it's a big thing, but whatever. I certainly don't condemn it in video games, if it might even help prevent it in real life.
You need not answer this but I wonder what your favourite game in the genre would be? Or any that just cross your mind as enjoyable. I'd be happy to try any if I hadn't already played it.
