It's an awesome concept, your flesh falling off as you go. Dig it. Also, I absolutely love that your blood trail is left behind and you can follow that back to where you were. If it was just a regular line or trail guiding you back I think I'd say that'd be weird and possibly too hand-holdy but because it fits so well thematically I just love that as a mechanic. Outstanding game, even if I suck at it.
