How many things? ALL of them! ;-) Probably about 20 or 30 if I remember correctly. It was pretty entertaining in the end when he was missing a few and wasn't quite sure where I stashed them, and ended up crawling around the room from one side to the other back and forth while impaled, trying to find the last one or two items required for his release. Maybe I should have added a time limit and some form of electro punishment after the time was up, to be increased every minute or two until he completed his task? Thoughts?
