This is a devilish idea that combines SAW-esque concepts with roleplaying mechanics. My favorite thing is the latitude given to dream up cruel rooms or solutions on both ends - but there is always a price to the player. I think that this could be really fun with an imaginative group. I think the only feedback I can give is, like Chiligoat noted, there is some need to adapt on the GMs part and fill in the blanks based upon what secrets/responses the players give. I think this a a really neat idea!
