Up until now I plan for those options to have an effect in the future.... And I don't think a WT is needed, next to the options there are (or will be, I remember that I added it in some choices) something like "Yes (NTR route)" or "No (Vanilla route)" and so on
Yes, that's good and I already saw one of those "commented" choices:
Which means i was lucky and chose the right options before, since i am already on the NTR route and i'm asked if i want to stay on it or move "back to vanilla"
However it is not clear to me why you combine NTR with swinging in one route. NTR means "cheating" while swinging assumes that a couple has sex with others because they both agreed to do so, which is by no means cheating but in western terms it's "open relationship" "hot wife" or "sharing". And in japanese terms its netorase , not netorare..
It even looks like you intend to also include cuckolding on the "NTR/cheating" route, although that's also something else than cheating, because the cuck is usually present when it happens so, it is not done "behind his back".. But OK, that may still be considered netorare, although it can also be considered netorase.. so let's wait and see.
I guess I'll have to play the game, because there are so few games that include swinging that I will just have to take the risk, in the hope that your understanding of swinging is the right one, which is more like "wife swapping" (2 couples exchanging partners) and not just some 3somes.. Good luck with the game!
