Looks like the "NTR" content will be removed, according to the latest Patreon post. Doesn't seem like it will be an optional thing. Looks like they're just getting rid of it. That's disappointing. I don't believe in forcing "NTR" on anyone. Some people get triggered by even the mention of it. But I'm always a proponent of giving players a choice. If they like NTR, they can see it. If they don't, they can avoid it. And I mean, completely avoid it, not just simply not seeing it (since I know that triggers people, too). Hopefully they'll reconsider, but these updates come very far apart, so I'll probably just put it on the backburner for a year to see how it develops. I was digging the game so far (even if the MC is frustratingly stupid), but it seems like it'll be a completely different game by the time I revisit it (especially if they remove all "NTR" content).
P.S.: Was disappointed at the tease of the sis blowing her (ex)boyfriend at the end. Would have liked to see it happen, but I suppose it's a nice teaser for the next update (unless they remove it like they seem to plan on doing).
