I am prolly the biggest amateur when it comes to game development but the best when it comes to feedback. Bottom line is no matter what kind of update the game gets, there will always be some who'll whine and bitch about it. Some are extremists. Either loving the ntr tag or hating it.
with no real intentions of belittling this amazing looking game, if you wanna balance between the NTR and non-NTR routes, i think no game has done it better than The Tyrant. The dev could look to that game for some suggestions, i think. Or just say fuck it to everything and take the game in the direction you want to, it is ultimately yours.
No matter what, the people who like the game will outnumber the haters by a large margin. I personally, prefer the NTR tag more but don't mind either routes.
Edit: after reading most of the earlier posts, i can't help but agree that trying to diverge and get a non-NTR route at this point wouldn't really be appreciated by either of the fans and this game might end out losing both of them. The NTR ones would expect you to continue on the same path while the non-NTR ones would be put-off in the beginning itself and continue to be vary of the game and future updates.
2 suggestions i can think of is:
i) Either revamp the whole game to include non-NTR path from the start (not really desirable or feasible imo)
ii) Continue on the NTR path to make one of the best NTR games (clearly feasible and desirable!)
the rest is up to the dev/s and what they see fit
