I saw its use as a tip of the hat to "2001: A Space Odyssey." Much of 2001 takes place in a sterile environment which eventually becomes a killing field. In the same way the Escher-like stairway in Squid Game (I believe the only place that piece is played) also turns nto a place soiled by blood.
interesting that you went with 2001, i def see kubrick but i figured it was more clockwork orange. Take a game that is known, then adulterate it, and for what? for the enjoyment of someone else.
