Luxee's own website presents Nea as just another character and makes the game sound like a standard dating simulator type game or possibly harem thing. Then the game itself starts with a scene in the future where they purposely leave it up in the air who the MC ended up with. I think it's only through playing the game or from reading these threads that you come to understand that Luxee wants Nea to be the primary love interest. Although they've also promised that Nea will be optional and/or avoidable too, so there's that. At times they seem to have forgotten that Nea was just supposed to be an optional path. I think they intended to make a true dating simulator game but couldn't help but give Nea more focus despite their best intentions. Nea or a trans character in general has been where their interest was for years.
Thematically, the love story between the MC and Nea that Luxee is building doesn't even match everything else going on, which is just a fuck-fest. I'm not pursuing Nea, but if I were, it would feel weird to have her story going on while I'm (unavoidably) nailing Alicia at school and chasing after a bunch of other women who I don't seem to have any romantic love for. It feels like two very different games are being mashed together and it just isn't blending well. I kind of get the feeling that Luxee doesn't have a good roadmap for this game, and they're not sure where to go from here, which is why they're struggling to find interest in working on it. As it stands now, we're several years away from the game being finished at this current pace, although I suspect it would be abandoned long before then. I'm still suspecting we'll see Luxee start up a new game at some point and just work on that instead or divide their time between that and A69. At least with a new game there would be some momentum and freshness, and they could avoid some of the mistakes made with A69.
