I'm aesthetic-twining and trying not to sulk
Oops it's technically a bit of personality quiz

Player navigates a surreal carnival, individual choices pebbles that tip the scales towards being one character or another, the final chapter (and answers uncovered) change depending on who was being "played"

With a finite set of like, actual characters/people who were at the carnival at the time

Weird semi-liquid identity exploration, basically

The actual in-story reason for this is that the player is a spirit-type-possession in search of a body, trying on lives until one fits.
