The gun is mostly supposed to be a red herring, and a way to kill yourself to get a specific death mini game depending on the time you kill yourself. A successful audio lure will beep when it "catches" Trollge, and a different beep when the Trollge reaches the lure. Turning off the light on works when he's not "aggro" which you can tell by his animation while at the window. When he's fully aggrod he'll start breaking the window.
I did try to broadcast some of the mechanics through these methods without holding the hand of the player. However I do thank you for the feedback.
