For the few, or a lot of people who hate NTR, do not rate, nor play this game.
I played the game, just to see why so many would whine/hate about it, and I never ran into one, NTR scene. Sure I may have just chose different choices, or maybe it's not implemented yet.
If you're one who doesn't like NTR, then just don't play games w/ the tag, don't comment, nor rate. Games with the tag "NTR" are for those people who like it.
I don't know why so many shame others for just having a fantasy/kink/fetish... It's like anime (since most who play VN's like it), you like anime, and people who don't sometimes hate on it in-front of your face, and you either sit there, or try to explain to them it's not bad... It's the same for fantasies, kinks, and fetishes.
I think every VN creator who implements NTR would have their games viewership sky rocket, okay, maybe not SKY ROCKET... but still. Just make it optional at the start of the game, so both parties can be happy.
As for the creator, keep going on creating this game if it makes you feel happy, or as if it's your passion to create these games.
The quote of the day (lifetime): "If you don't like something, you cannot rate it" (It's true, you may not like steak, but that's a preference, if you do like steak, then you can do a tier-list about them, on which one is better... that's the best example I can give.)
