So, I finished the game despite being unable to save the latter 1/3 or so. Hoping an update will fix this before the next chapter.
Overall, this installment met all of my expectations except for keeping the "reveal" conversation between D and Elena confidential. Then, checking out the "harem" route, I could see that they used that setup to further Elena's parallel path in a reasonably creative fashion, which was cool.
And, as anticipated, Elena did indirectly contribute to their consciously considering PinV by her mere suggestions and repeated suggestiveness, I feel. That final D and MC sexual act was the result and we know what's on tap for the next installment now: some type of penetrative act will become the center of focus that they more rapidly swirl around. At the same time, they are more openly and deeply wondering about how much love/romance they can attain and what the various possibilities will do to their individiual and shared happiness, given the logistical constraints still before them.
Meanwhile, on Elena's route, she went from a gut "love" feeling for MC to wanting an explicitly sexual role with the pair after reconciling that she will not be MC's primary love partner, which was entirely in line with her supportive but horny personality to all along. Given those moments where she admitted to herself that her adult future is uncertain (i.e., lazy, no skills) and the further evidence we saw that she really just wants to feel satisfied without working too hard most days, I think her falling into a mode of consciously accepting being the third wheel in both the D-only and harem route makes plenty of sense.
I liked this chapter, just want the save bug to be resolved and am unsure how to contact the Dev team directly, since my payment via the Buy a Coffee route doesn't offer a help line to the team.
