Thanks for your comment.
It is indeed a bit overwhelming when you're just dropped right in the action, and while a tutorial was planned, I didn't quite have the time to implement it in the end. Also why the traits were added in the description of the game, instead of being directly explained in-game. (Although that one is fixed already, and will be deployed once the jam ends)
For a quick explanation, the goal is to spook all visitors. They're spooked once they start running really fast, it means their sanity (the blue bar) has run out. Elite guests are simply any guest with traits, they show up in the monitoring tab and are the important targets to look out for.
If they leave before you spook them, they escaped.
