I think it just does not really tell much. I have had gender dysphoria since like... ever, and I haven't really came out as trans outside of the internet.
I get what the game goes for, seeing how much pain it goes into not being able to live comfortably as a female when you have a male body and people associate you with a male. Even then, I think that it is just... not as crazy bad as the game tries to put it with its music and such? Everyone in the story except of a girl was really respectful to the protagonist and she kind of antagonizes them. I see it as a way to emphasize not things like transphobia but instead how the protagonist fails to feel comfortable with herself, which is fine, but I was just expecting something much deeper when the game threw that text of "don't play this if you are dealing with depression" and such.

Just to make my point clear: I think that the game should make a bigger effort to let people who have not experienced gender dysphoria know how it feels. I certainly know why the protagonist feels how she feels, but I think that a person coming to the game without knowing it would not understand why the protagonist is suffering so much from apparently normal conversations. I think that a bigger emphasis on the protagonist's feelings and let her explain how and why she feels would have made for a much better experience as educating people on gender dysphoria, and I think that should be the focus since for any trans person this does not really add anything new or really interesting.
