Sorry that your favorites didn't get as much attention as you'd like, but I have to make content for all characters, while also telling a story, I can't and won't be able to satisfy everyone.
People want to eat the juicy burger, not the soggy leftover fries in the bottom of the bag, especially in a game such as this, where they've been invested into the main characters for such a long time, waiting for progress. Focusing on side characters so close to the end is a questionable decision, story-wise or not.
Yes, one more big Story update before v1.0, then the main story is done, but...
That's.. two more big updates, and then those after-game scenes, and
then you'll be working on Tainted Heritage? Boy, that's going to be a 4-5+ year waiting time for an update for that game. I mean I get wanting to finish this project and then take care of the other, since juggling two games and real life is impossible as other game devs are showing (Looking at you, Ocean), but man.. feels bad to be someone invested in TH.
On topic: This game is a banger, too, with a unique kind of eroticism just like TH, especially true for both moms, but since this seems to be a side character / story centric update, I'll be sitting it out. Looking forward to seeing if the wait's been worth it when it finishes. Good luck to the dev.
