I understand your point of view and i'm not far from it. I respect all preferences and I know that we can't please everyone.
The story is my main concern in this game, that is why I did not make it harem or vanilla, because it wouldn't fit at all the context.
I have the ideas for that story for a bunch of years, I can't even recall since when, even before I knew the existence of adult visual novels. But it was on paper, or txt files, or comics but I have no talent for drawing
. With Renpy and Daz, I discovered a nice way to share this story with some hot actions which is even better. Plus I fell in love with Daz3D, so it's perfect.
I'm saying all this just to let you guys know that I'm making this game more for passion, than for the "industry", but I welcome every constructive remarks like yours and will consider them as long as it doesn't change the general storyline and atmosphere that is the core of the project.
Back to your concern.
I don't know if you read my post 41 with the spoilers, it might answer your questions.
What I find confusing is that everyone has different definitions of 'NTR' and different definitions of "avoidable".
If NTR applies only to the girl you truly decided to go for, I can confirm that you can perfectly have a complete story without NTR with 2 of the 3 girls. One of the girl is more problematic due to her situation (having a BF).
If by NTR, you mean it has to apply to every girls of the game whether you romance them or not, then no, you probably won't be able to escape all of those and I don't want to limit myself too much by doing so. So I rather say there can be NTR. (as for the skipping scene option, I totally agree with you, but it's easy to implement so I will make it for those who want)
Well, i'm starting to understand the need for a walkthrough
