each of the shadow monsters are reflective of both who the boss is and how they died,you just look closely at their bodies and injuries and yes i added a bad ending pit cause i had one left over and wanted to do something special with it to give people a taste of what the bad ending will look like.if your wondering what the purple stuff is,its just an effect i wanted to try using to reflect the fact their shadows and the lines on their eyes?since this is fnaf based their a callback to how they were originally just crying children
fun fact;in the original comic i made i originally had hades be the culprit of the deaths but i realized that was inconsistent and not at all a good idea,so i changed it to william afton since ya know the man behind the slaughter memes :)
