Happy to see all the excitement around this gem! Funnily enough I have worked on a game "Tiny Brutalism" couple weeks ago as well. "Great minds..." :) You guys nailed it.
Collected my thoughts in a video:
Hey. Really cool that you shared these thoughts. There's definitely a lot of approaches to take with the genre. Still countless other potential combinations to explore. It's interesting that you both looked at it in different ways. Really, you can take any architectural style, combine two, or even more interestingly, invent your own.
