I finally sat down and played this game for the first time all the way through, and very much enjoyed it. The few things I didn't care for were far outweighed by the different things I liked and loved. So it's definitely a "keeper" for me.
My understanding is that while the game's status is "Completed", because the canon ending is done, quite a few of the other endings are still being developed and are considered to be upcoming DLC.
I saw that some endings basically had placeholder images until those endings get properly made and added. But there were about 5 other endings (6, 10, 13, 15, & 18) that I didn't even find placeholder art for (IIRC the "Alone" ending is basically an unofficial "19th ending"). Are these basically mystery endings, and we don't yet know what they will entail, or did I just miss them somewhere?
Besides just curiosity about the others, another reason I'm asking is because part of me is really hoping for a proper Hana path/ending (Hana & Iona both would be even better, but I'd still really like one with at least Hana). I know that she said she's not interested in a relationship with the MC, but that doesn't necessarily mean anything definitive. Twists aren't uncommon, and people change their minds about stuff all the time for all kinds of different reasons.
So TL;DR has it been said or suggested anywhere what Endings 6, 10, 13, 15, & 18 will entail? Or did I just happen to miss those?
Actually, now that I think about it, I'd also really like to see an ending focused on Maria, or Maria & AmRose. That sharing scene of her in the bathroom/gloryhole and how hard she was getting off on getting degraded and humiliated was hot as fuck. If there was an ending focused around her going down that kind of rabbit hole, but exclusively to you, or of you and AmRose basically keeping her as a pet, that'd be pretty awesome (imho).
