>>16264well, i don't have anything specific, as i haven't reached the second half of the game yet, but my number one is that the flow state exists as an actual world, rather than just as a figment of sabitsuki's imagination. the characters in there have lives of their own; smile, with his sister, the patrons of the sugar hole, oneko…
another thing is that the building in the moonside-esque neon world is a love hotel. i know vaguely of some area called the hole in girl map? and the vomitgirls area is something i've heard talked about in reference to it being an allegory for prostitution
