i have got to read this from the starting all over again

i have the basics down like i get the gist of whats happening the lore and everything but i wanna look at stuff from different angles and more in depth so im gonna go back to chap 1.
also it's clear the entire gang are players and their tapes are their memory/progress (meaning there are a total of 6 tapes?) and they all have special character traits. so why are they at each other's throats when they should be collabing together? is doha like a wild card player? is he even on the other characters side? cause so far he's only trying to drag on the game cause he likes to do the deed with pi bada lmao.
doha is sus and atp theyre just playing amongus
