I think this idea is super cool, Gen! Taking the theme of "Non-Human POV" and making the goal of this game be to find out what you really are is a super clever way of flipping the theme upside down! I enjoyed playing through this game a lot, and I was very glad to get the good ending on my first try :)
These might be very minor things, but in terms of critiques, I think the controls feel a bit slippery (?) because I notice that letting go of a WASD button after walking makes me slide to a stop rather than stopping right away. Perhaps this was intentional, but I personally think a hard stop would make things feel a bit nicer overall. I also personally think the mouse controls are a little too sensitive, but that is just my personal preference anyway.
Lastly, I think some sound effects would have been nice, but I am unsure if you meant for there to be no sound since you credit the NYU Game Center's Audio Library as a source for sound effects in your description. Regardless, I think some nice music definitely would've fit the style of this game very much!
I don't think there's much else I want to say though! I liked the art you drew (and the fact that they stand around Paper Mario style) and the fact that the point of this game is to just walk around and talk to people in order to discover your identity. The act of going around and talking to people is very chill (even though the story can sometimes shift to be more dramatic), and the whole idea of this game could lowkey be symbolism for real life--sometimes you need to go out there, meet and talk to a bunch of people, and do some self-reflecting to find out who you really are! Wonderful job, though, Gen! I always look forward to playing your games!
