I'll be waiting for Chester's epilogue to come on itch. What you're describing actually can look strange. But I can't judge it yet.
As for the other points. Threesomes. Are you sure they're really implemented awkwardly? It would be awkward if Chester wasn't the third in Dozer's route. That would be awkward, wouldn't it? XD And if in Harold's route, the third one was not Richard, but for example Diana))) Did you get my point?)
And about good and bad ending, as we've already figured out, you don't have to indulge fetishes (how TS mentioned it) and do what you don't like. This applies to many aspects. It's great, isn't it? Everyone can take from the game only what they like. And here we come back to your comment. I personally haven't heard any specifics about what you think is awkward and what should be paid attention to. That's what I didn't get.
Or did I somehow misunderstand you and the whole point of your words is that you wanted threesomes, but you didn't like what the game offered you? Anyway, it's pretty subjective, don't you think so? Maybe you didn't like the implementation of these moments because of your personal qualities? Have you thought about it? How should it be to satisfy you? In that case, do you have any suggestions for Dyne, how could he have done it better? I personally did not see any problems in implementation of threesomes (except that there are none of it in the game. kind of. at least if compared to Taigher_28 artworks. that is threesomes!), and I would also be interested to hear another opinion and look at the situation from the outside.
And I'm sorry if my words look too aggressive and arrogant, that's not my goal (at least in discussion with you)
