I played through the demo and poked around some youtube playthroughs and as a queer/non-binary VN writer this feels like it's like 80% of the way there, but ultimately misses the mark. Even if the intent was not to make the cast trans-women, the strict adherence to she/her pronouns and referring to the cast as women all the time makes them virtually indistinguishable other than one or two cutesy lines about "what's under their skirts." Even the purple-haired character's sister calls them "sis." It feels like I'm reading a conventional dating sim where the girls have flat chests and penises and that's literally the only difference.
I really do wish y'all the best and appreciate the effort toward creating more content like this, lord knows we could use more, but I would implore you to find some LGBTQ test readers, especially within the femboy/crossdressing community. I think there are a lot of very fun ideas that I'd love to see in a visual novel that you wouldn't see in a conventional dating sim. Have different characters prefer different pronouns, with some insisting on he/him and being called a guy. Have a newbie that keeps slipping up and doing masculine things or falling into a deeper vocal register. Show characters presenting masc outside of work. Show the drama of characters needing to hide this aspect of themselves from friends/family. There's a giant elephant in the room with "gender" painted on the side in big block letters, and if there's ever a place to stop ignoring it, it's here.
Of course, this was all based on the demo content and skimming some paths from youtube playthroughs. If there are any routes that tackle gender identity in some meaningful way, please point me in that direction and I will gladly buy this game.
