‘The Binding of Isaac: Afterbirth’: Our Ongoing Love Affair with the Twisted Mind of Edmund McMillen
The evolution of this game corresponds to the core idea of Isaac himself, a steadily growing monstrosity that becomes continually more twisted and more interesting with each gross addition to itself.
In The Binding of Isaac, the monstrous body may be ugly and awful, but it is unique, free from established rules and stricture, free to continue to grow into something other than what others desire it to be.
In The Binding of Isaac: Rebirth, the body is wrecked and made ugly for the sake of freedom from fear. Instead, it becomes something fearful in its own right.
