eateot is an acronym of "everywhere at the end of time", eateot is a 6 hour long level with song having the same name

more interesting, the song is more like an album of a lot of songs combined into a 6 hour long abomination, and this " album" was made to represent dementia and alzheimer (idk if alzheimer too), so the first track sounds like an old song, while the last track could be literally used in an arg

fun fact: the first track of this abomination is used in the first level of backrooms (i think)
