Well, good for you to keep hope.
Personally I'm not really attached to this game since it's been more than half a year since last (small) update, Emma romance is progressing slower than getting US back on the Moon since the author wrote himself into a corner by making her sexually/romantically naive on the level of a child even though she's 19 and thus honestly can't really progress a romance with a FAR older man in an organic/somewhat believable way. And until this update dropped I had both forgotten about this story and given up on it being updated or at least with any significant progress in the path I'm mostly interested.
I don't think we're gonna get much more from it; the fact that we didn't even get the entire freaking update in one go is already telling enough for me, besides his explicit declaration that the game is toxic for him and he's giving up. Hell, I'm even doubtful about the second half of 0.15. If he comes back to the game, great; but I'm not holding my breath or my hopes. I would most probably simply suffocate disappointed.
I like this story, but it's not important in my life, not like it seems for some people on this board who are very passionate. I follow just 3 or maybe 4 AVNs, sadly all have authors either working really slowly to the point they cured me of passion for their work by making me indifferent or they are on the verge of giving up.
If the author returns, great, but if not, it's not I lost anything important to me.
