This is probably one of the more creative uses of the theme, and I really liked it. I'm a sucker for investigative-type games. And this is another distinct type of VN coming from you, which came out very well. The concept of history/stories being told, rewritten, changed naturally based on personal belief, bias, ideals, memory, and agenda is something that I, as well, thought of when thinking about this theme.
I liked the story told, and I did not expect there to be two, which was pleasantly surprising. I don't have much to say other than me really liking this a lot, and if there are any issues, it would be spelling errors like "responsability." Also never heard of Mx used as an honorific before, and my unwoke ass thought it was a misspelling of Mr so that was a good lesson learned.
Also heck yeah, trans rights. 5, 5, 5, 5, 5.
