this is... wow... this is amazing! But(SPOILERS!!!)
they repeat it so much "you're a girl, you're a girl", makes you really doubt it from the beginning:).
also is the original in japanese? Where can i find more info about that "Colonel"?

Yes, I like how it comes off quite unnatural, it certainly makes the reveal feel less like 'oh wow, surprise!' and more just a sad confirmation of something you've likely already realised.
The original is Japanese, yes, as linked at the bottom of the page under 'Other Versions' ^^. Colonel's Twitter is written in the game readme, so feel free to drop them a message if you liked their game!
