Alright so lets get his straight:
-Players use a signup form and create or take a role for one or more characters
-Then the game begins with them all waking up in an asylum
-They dont recollect any of their memories but all know one thing: "they have to get out of there"
-Players use *....* to post their actions as they navigate through the asylum
-As they do so the game master (either me or you?) puts obstacles in front of the players to either kill them or hinder their movement.
-For completing an obstacle the player may just be allowed to live or move on or they might get an item that can help them in the future (ex. flashlights, lighters, and other survival gear)
-Once a player reaches the exit of the asylum they meet you (aka the wacko that brought them there? and your minions)
-At this point im unsure of what happens but id have to guess a face-off of some kind
-Some may die in the faceoff so whoever beats you first is the winner and receives an emblem
So something like that?
