Thank you for the consideration, I always appreciate when Game Developer is taking time to plan about their game. other than this, i'd like to ask how far the depravities may go.
Like, would there be hentai level gangbangs, beasts (or something), having sex while you're alseep in the same room, having a date while cath's full of semen, etc.
As for something I forgot to mention, since there will be Netorase and *possibly* a lover route in the future (a tradition in this genre), I'd like to suggest a way to "mix" events of different routes, there will be people who mix up their own routes in these types of games (I admit I am one of them)
Like someone maximizing both the amount of NTR sex as well as Pure Love, or maybe they liked an event in one route and wanted to include that in their run in the other. this might be a little tricky to implement, but this essentially boils down to what kind of kinks they want in their route or endings.
And if you finish the stuff you want to finish, you might even add "Mini Ends" to some decisions, like if cath got pregnant by the friend or if she knows who the father is at all, that might add some details in the ending that changes its subtext in addition to the route. But this is some late stage stuff, I just want to put this out there, since it will add some replayability for a (relatively) small amount of effort in story writing.
(though, I understand if that's hard to code, this is a "finishing touch" type thing so you can ignore that for now, I don't want to put pressure on you.)
Again, I thank you for making this game, I like it so far! 👍
