Don't have time for a proper review, but I'd like to say that this is wonderful. Choices have consequences, which is surprisingly rare, especially with so many of them. Often all a choice is in other games is a small dialogue change. There are really only two issues that take me out of it, and I'm sure others have already mentioned them. In order of appearance:
Firstly, there's the word choice: Very often, incorrect words are used for things, which are close to or sound similar to what the author actually intends (I presume). It's far from a deal-breaker, but in the currently available build it is pervasive. I understand from prior comments on this thread that it's being worked on, so I look forward to the results!
Secondly, there's the MC in porn clips: Sometimes - especially in Chapter 2 - the actor is obviously ethnically different from the usually-"white" MC. The problem isn't MC being "latino" or "black" or anything like that (in fact, some of my favorites fit those descriptions) but the inconsistency breaks immersion. I understand it can be difficult to find good clips to use, especially while keeping the actresses consistent (which is admirably accomplished btw), so some divergence in build, age, hair color, presence/absence of tattoos etc. is to be expected, and if there needs to be inconsistency then most would agree keeping the actresses consistent is more important.
Otherwise, this has real potential, and you're on the short-list of people I'd support if I could. I know, platitudes don't put food on your plate, but it's all I can sincerely offer.
Cheers, and good luck with the project!
