Thanks, Maxime; am I guessing correctly that English isn't your first language? Maybe this is a bit of a translation issue. :)
The gender choices were developed after speaking with a bunch of transgender, non-binary, and intersex writers, game devs, and players to try and give a good balance of choices for everyone to pick from. Androgyne in the game is closer to non-binary, whereas "hermaphrodite" is considered an outdated and potentially offensive term. The gender choice, ultimately, has little material impact on the game itself and is just to give players more representation to enjoy the game however they wish.
As far as what the game itself is, I think if I call it an RPG people might be expecting something like Zelda or Diablo, and I don't want to give anyone the wrong idea. You pointed out that there's not much gameplay in the video — that was the Kickstarter pitch (I'm working on a proper trailer at the moment!) so it's slightly different, but it's difficult to put a text-based game into a video format unfortunately. I'm working on it, though! It's closer to an RPG than a visual novel, I think, but it's not quite either. I don't mind what people want to call it as long as they enjoy it, though. :)
Why are there graphical artifacts in the texts?
I'm not sure what you mean here, could you possibly send me a screenshot of what's happening? That's not been a bug that other people have reported so I'll see what I can do. If you can't attach it in an itch message, you can email joshua at alcyonegame dot com instead.
