I'm Baack, And I've got a new one for ya. Now you may or may not be aware of this much, but I like to screw around with
Bald Bull. And i found something interesting.
http://imgur.com/AosOqObserve the Location we are, Where i Am, and the fact that he's stuck. The minute you enter the room, you can easily re-jump out of the room and do whatever you want because all of the other triggers don't seem to work. Don't get me wrong, you can still die from spikes and stuff. (
Personal Opinion Warning) I do believe you should make it so that a sort of cut-scene ensues where the kid walks to the center to make this not possible. That or simply place invisible blocks over where the door is after the player enters the room. Or leave it be, I just want you to be aware of this.
