Chapter 1 starts fist, once we're done leave the chapter and skip the cutscene. Chapter 3 next, as it's a cluster fuck. Continue until after chapter 5, leave do chapter 2 then finally chapter 6. This is just to make chapter 3 come earlier as it's a harder chapter. The rules say that inorder to finish a run, we just start at chapter 1 and end at chapter 6.| Sorry if this is a mess. I'm going mad

It wasn't specified, but I don't think it would count

I think that runs should maintain chapter order as you wouldn't be able to do them out of order if it were your first time playing the game
