Really happy with the Chapter 9 update. I love that most of the crew now has content! Celine's reaction near the end of the chapter causes me a bit of concern, though—will it be possible to reach a "harem" outcome where you can romance as many of the crew as you'd like, without anyone getting jealous or closing off? I really liked that aspect of Sisterly Lust, and hope that it would be continued (but to an even bigger degree, given this game's cast size) in TftUV.
My only "complaint" about Chapter 9 was that it was over so fast. I'm eager to see where all these character relationships go... and, of course, for more of both the sex scenes and the plot! But that's really not as much a complaint as it is a testament to the quality of your work, and I certainly appreciate all you've put into making this game.
I also was just the slightest bit disappointed that the scene in the cave didn't involve more Nadya action, even while the PC was fucking Caese. Just a shot or two showing she wasn't actually asleep, but very quietly masturbating, would have been so hot. But that's small potatoes, and I'm sure there's plenty more hot sex scenes in the game's future. Can't wait!
