Something i havent seen anybody asking about Binding of Isaac Rebirth is what would it happen to the cutscenes, will they look better, be more in-depht to the character, will there be more, or would they be the same but redone in 16bit? I personally would love more varied endings rather than them being Isaac showing the item you unlocked kind of how it shows when you first beat mom. Will we know more about Isaac dad?

we are working on that aspect of the game now. 

there isnt anymore to the “on paper” side of the story with isaac so you wont be seeing anymore of those. but there will be more cut scenes and changes to the old ones and aspects of the story that are filled in.
