seems to be a start of an idea, though a little unsure, it does feel very incompleted.
my guess is that there was supposed to be an enemy or outlaws that will attack the people and your job is to find and save them while avoiding the enemies that are roaming round the map trying to attack your or the people.
if there was more time, I would be more than open to play such a game, but as it stands, it wasn't fun to play.
