Hiya! Some stray thoughts i wrote while reading this one below!
Before even opening it, the name... nothing strikes fear in my heart like having to consider mathematics in >3 dimensions, so i'm already scared
first thing i notice -- trying to fly away brings you back to it. even when you're outside it, you're inside it. good stuff. impossible geometry indeed!!
I like that the horror loses proficiency as you plug away at it.
"no breathable oxygen, but not a vacuum" has me wondering what IS the atmosphere in here. cool. (not asking for an answer! i just like that it's making me ask the question)
hahahaha oh my god all my nightmares come true as i flip to the map! we have left the third dimension. this is very, very cool. if i'm reading this right, the fewest moves back to a room i am currently in is... 6? which means even if i am wandering around confused, the odds of me accidentally backtracking are low (and might actually require, like, my understanding of the layout/backtracking on purpose). very cool implementation. and that also lines up with the introducing of the horror after 3-6 rooms to keep players on their back foot.
layout here is wonderful work. you've made a very easy reference for wardens to determine what players see.
feel like i am gonna be thinking about this one for a while! nice work!
