I really like the unmaking mechanic. Looks like everyone gets two cards, and thereby two chances to stay in the game.
I think I would change this mechanic to modeling clay and remove major sections of the model and smash them into a ball. THAT would be challenging to restore.
It also seems like the "psionic radiation" has affected everyone's minds and they believe they see what is described, but in fictional reality it's just normality trying to reassert itself on the damaged brains of the pc's. Still, looks like great fun.
