There is also a new branching point on the Netorase path, by talking to your Mom in the kitchen you can approach her and pick to watch only or want to join in an these have different scenes.
but it does mean at least 3 save files for all storyline but the pure NTR path only has one difrrenent scene for now that path is not the focus yet it seems.
Sorry as much as I like helping out, in subscribed games I am in I have seen too many people be kicked or lose their sub for sharing, I support this site and what it does but normally leave the sharing of games up to the game share mods or devs themself.
I can tell you over on kemono the dev's Patreon is updated at a slowish pace but I assume the new version will be on there soon as well, not sure if there is an update request section over there. It is possible.
