Yeah bro, I do agree with you, something that I would like to add, basically to improve the first stage of getting to know each other to create more attachment, I have some sketches I did about the new systems that would replace the current talking, It's designed like a minigame that would provide some well-required extra pacing.This is what would intrigue me about a format like this.
The minimalist format was intended to be built upon, and it provides a very strong foundation.
Repeatable events are nice and all but variable animations and variations on how she cheats would improve it, but I think what would make things interesting is if there were a challenge of getting her to begin with.
I know it's an E-girlfriend game, and the theme is control, but I think at least fighting to get her, and the horror of becoming a cuckold in any form would make me way more attached to this game.
NTR is great when it gives you a rush, when it feels real.
The art style and renpy engine work well for that, but stakes make everything.
The day I do that update I'll be really happy
