yes, i have. when i sent out invites, i also sent out their "identities". When they got here i had them all pull a slip of paper that said how they were related to the person who was murdered and if they were the murderer or the murderer's accomplice. the murderers killed people by blinking twice at them originally it had been winking but the accomplice couldnt wink. then you just eat and wait for someone to die/find the murderer. the person who found the murderer got a cake. it was pretty simple oh yeah, nametags help
