i've never taken math any higher than pre-algebra and just know lots of time theories related to infinity

but if you're gonna talk about infinity *and* the rooftop existing and not existing at once, then the rooftop could be all of us. we could be the rooftop because the "number of floors" is decided by us when we choose our rooms, thus we are the infinite factor in moss's equation

using moss's equation wording it'd be something like...

rooftop = limit of apartments

number of floors = infinity

number of floors = determined with each room chosen by us

each room = determines the number of floors

determined number of floors = decided by us

decided by us = infinity

us = infinity

infinity = rooftop

not sure how much sense that makes all i know is i play zero escape way too much
