From what I've heard from the developer the NTR is completely avoidable and it happens like this:
Ako seduces you to get information about the Heroines => you accept her advances and tell her what you know about them => she tells the gang leader (the ntr guy) and he uses this information to get closer to the Heroines.
So as long as you don't get swayed by Ako advances you are completely safe and both Rio and Lilian (the other 2 villainous Heroines) are not related to the NTR elements at all so if you got seduced by them there isn't any affect on the Heroines, and the developer recently confirmed that you can actually be seduced by Ako and still prevent the ntr from happening (which can be kinda hassle as you're going to have to find the Heroines in the city and prevent them from interacting with the gang leader) anyway the latest articles were focusing on ntr elements is simply because the main topic of the earlier articles was the villainous Heroines and the seduction scenes also the ntr were changed to some degree in the game so he has adjust that as well, not to mention the battle system and the consequences that will follow after you lose, as the Heroines will be subjected to different kind of humiliations, and if that continues it's a game over.
That’s what I heard too, but the problem is all these updates? it’s just that, a lot of them and I do mean a lot of them are all NTR foucused. To the point that it seems like there’s a lot more ntr updates than other features updates. Which is a bad sign.
mainly because just look at other games with‘optional NTR’ sure it’s avoidable on paper. But in execution choosing to avoid it pretty much just result in making the game feel more barebones. And that’s because of how much effort and time and artworks are NTR in it. To the point that the other content in the game is feeling lacking.
I wouldn’t have a problem with the dev adding it in. But you kind of just spoke about my concerns. Go back and read those original articles and then read these new ones and then tell me which ones seem to have more attention. And depth given too it.
Very few games have ever been able to actually have a proper balance between ntr and non ntr content. And adding it in is pretty much every single time the first step to a dev becoming an NTR game Dev.
