Super cool game! I was so sad when I reached the end, and I'll definitely stay here for new updates!
English is not my first language, but I think I did see a gramatical error, where instead of ''you do X'' it was writen as ''do you X'', but it wasn't supposed to be a question. Im really bad remembering stuff, so I can't be more specific, my apologies.
About the MC and story in general, I don't think it was overly femenine nor cis. I am a white trans nonbinary person, so I can't really talk about poc representation, but from what I've seen in other comments, everything checks out!
What I would personaly change is the gender choosing.
Instead of
''Man
Man but was assigned Female at birth''
I would say
''Man and was assigned Male at birth
Man and was assigned Female at birth''
Just to not separate so drastically those two.
However, I think it would be easier to just say
''Trans Man
Cis Man''
I don't think what you wrote was offensive or transphobic, I felt everything was really inclusive and comfortable to read for someone who doesn''t get that much representation, I just think it would be easier and more comfortable to read as a trans person.
