Your entry has a strong message, I really like it.
On the technical end how did you achieve the procedural missing tiles, I’ve been trying to step up procedural game and also want to go for a missing tile shader. I had difficulties getting the effect and asked on Node value not correctly read by bump - #6 by Le_Pirate
I got it to improve a bit from the advice I received but your result is much better particularly the walls on the sides.
