I was confused when I was told the girlfriend would be able to be excluded from interactions. The entire intro has every futa all over her. Only get to exclude her after everyone got handsy. And "being able to choose not to see it" still had all the implications of something happening. That's not a choice to exclude NTR, that's forcing it, and then asking if you want to continue. And then, after skipping through all that, to choose to work solo, the game can't even run. Thing is a botched mess with a lie that the polarizing fetishes are avoidable. Fuck this project.
Well I do agree that the whole intro makes little sense (because it doesn't give the player the choice to act accordingly), because there is absolutely no reason for them to even agree with their girlfriend being alone with those characters (Doctor, Hypnotist) let alone to accept anything from Tina - who they were warned about and who quite literally immediately shows the warnings were justified before even offering the coffee .
It would be better to either not even have said girlfriend to begin with (as an option for players to pick, not mandatory because others do like having her around) or at least to go on the entire trip alone.
But that is partially due to the fact the story is kinda nonsensical so far (we aren't given the reasons for why the MC is even there and so on), the protagonist has no personality yet and also doesn't really act like the resemblance of a human being so both (protagonsit and girlfriend) feel pretty superfluous in their own right. The girlfriend existing makes 0 sense for anyone not interested in the NTR stuff, but at the same time she then kinda is in the way of enjoying the potential lewd stuff that doesn't even include her. Having the option to just not bother with her existence at all would be extremely easy to implement (since she could just be removed from the intro) and not take away anything from the people who love NTR in the slightest.
Edit: I wanna add though that these don't really make the game "unplayable" (and I say that as someone who doesn't like NTR at all) it's just more of a crude workaround right now instead of a real alternative. Would be nice to see it addressed but that's about it, technically speaking there isn't even a reason to play the intro anyways so by skipping that and then having the girlfriend not interact with the cast does mean there isn't really any NTR going on.
But it has to be said that this is a leaked version of the game, not meant to go out publicly, so yeah ofc there will be some noticable bugs, also this is in early development, so I think the Dev deserves more patience than calling them a liar about the option to avoid stuff, it seems more like a lack of polish and also probably some stuff has to be brought up to really sink in as a potential issue for people not into certain things, it can be easy to loose track of that during writing, coding and creating the visuals.
Don't think they mean any ill by it, honestly.
