Improbability Drive?
It's amazing how Madness has evolved. From a simple flash animation light on plot but heavy on violence to this. The beginnings of a huge story-arc and explaining just how The Protagonist keeps coming back; he's simply not allowed to die. But why?
By the way: was that the Improbability Drive button taped down where he found Clown's note? Nice little attention to detail that only long-time watchers would pick up on. Kudos.
