i'm curious if luxee made that tranny character to draw the phantom audience to his game?
It seems to be their own personal preference. They really wanted to add a transexual character to Parental Love. They put it to a vote on Patreon I think, and got voted down by a wide margin. So then they came up with the idea for this game while they were working on Parental Love, put out the first update, and again put it to a vote if people were okay with them working on this one instead, or splitting time between the two, but again people voted heavily for continuing Parental Love, much to Luxee's reported annoyance.
Well, I like Nea but not like this(more friendly way), this is not my cup of coffe. Playing this game I fell like I'm foced to play her/his content.
Nea is a tremendously sympathetic character that from my limited interaction with makes you want to protect them. But like you, it doesn't go as far as a romantic or sexual thing. The family is kind of an afterthought in this game, which is kind of a disappointment coming on the heals of Parental Love. That wasn't a perfect game, but was still probably one of the best ones out there. I think there's optional incest in this game mainly as a nod to fans of Parental Love. Nea is the focus of the game, so everything keeps coming back to them one way or another, even if you choose not to pursue them. I'd really love to have seen a more conventional incest game come from Luxee after Parental Love, but I understand and respect their need to make what they want, and what makes them happy.
