jadih covered the gist of it.
Arc doesn't come around here so the discord server or itch.io page are the main ways to get to him.
I can cover some stuff too.
For starters. The choices don't matter
that much, provided they matter at all.
You may notice that some choices in scenes are really self-isolated, and don't really have a noticeable effect in the following events.
They don't, they're just that, roleplay value.
Although I don't personally remember him saying choices would matter, it could be something he said a long time ago.
Before he figured out he was biting more than he could chew.
Having 17 main girls and I forgot how many (over 30 at least) side girls.
Good fucking grief.
Also it's often mentioned how the girls used to have more stats aside from the love level.
Sluttiness, Submission and Exhibitionism.
Those apparently were on all the main girls and would've had their respective training.
Submission was in the dungeon and Sluttiness on the club. Don't remember if Exhibitionism ever had a training.
All that didn't go far before it was removed.
You can still "slut train" Gwen, Jessica and Chloe and the spanking scenes in the dungeon for Gwen and Jess.
But I'm almost certain that won't come back.
He did mention that the dungeon will have use.
I guess on characters like Morgana or Dhena, or other people that would we need to imprison.
Maybe even Chastity at some point, she's into BDSM.
I've gone this far on the ramble but the entirety of your post could be answered by:
"No, there won't be any significant amount of branching to fit that in the game"
And add to that a random quote from him about the subject.
