This is sheer brilliance, for its scope. I'd love to follow the development team- they seem very promising.
The first round, I didn't realize the soldiers' words (and the monkey's) were actually written by other players like me (They were well written, thank god). It's very interesting that way; you partake in the game in a passive way and you're left to wonder about your fate. Was it you they were searching for- the traitor? None of us were, but maybe all of us are. It's all about giving the player with the gun a moral dilemma, or 'helping' them choose. The monkey and the tied-up soldiers create the game for the one with the gun.
Nice music!
