hard not to want a girlfriend and have a baby with her :) it is the only three end I know.
For my fetiche, don't worry, I know other good game with it, and I have already writed about why I proposed it lower. (Don't know if you have read it)
Just the spider girl was an exemple, I know it is more Real than fantesy game, but you make cow girl and Sarah will, maybe, have her body part back, so if you come to have some patreons who like bodybuilded girls. You can do many thing with Rosemary skill, improving day by day, wonder what she could do day 300.
I was telling you that, in case you wouldn't have idea of how make some wish of yours patreons ( I am not because I don't have job, even before covid.)
And to "niche" (I don't know what it realy mean, Google don't want to translate it) but I suppose it mean it is to "soft" for the "dark" theme you want to make. But like the life is not alway dark, I think, you make the MC doutb if his make the good choise, sometime (like in the pool or day 50 at night). And like Rosemary don't Care about life, the old man "fall" to the dark désire, you can maybe make someone to help him stay with a human mind... (Maybe already did with Tanya or Eve.)
