Hello!
Thanks for all your suggestions!
Yeah, since it's a hentai game, I was going to be +18 no matter what I did, so the story was planned from the beginning to be darker.
Like I said, the major plot points are pretty much thought of now, but your ideas are helping me think of one of the plot points where I think they'll fit in nicely, albeit changing a few things. I also don't want to do exactly what you say because the story would no longer be mine and because it would stop surprising you and whoever reads this when they played it because they would already know what would happen. Still, I'll see how best to use your ideas. Thank you very much!
