Alright anons, I need your assistance. A while ago I got to the final boss (or what looks like) of act 2. I decided not to fight it 'cause it felt wrong, too soon. So I left and explored a lot, for example I got the double jump. Thing is, it seems like there's not much left, so should I fight it and move on? Or there's something important left to do?
I'm trying not to spoil/get spoiled. I got all the fast travel locations, if that clears it up a bit.
