It may be possible to take advantage of multiple levels of reality within the game itself to confuse or trick the gatekeeper. For instance, must the experiment only be set in one world? Can there not be multiple layers of reality within the world you create? I feel that elaborating on this any further is dangerous. Think carefully about what this advice is trying to imply.

This is a pretty clever way of defeating precommitments. (Assuming I'm drawing the correct inferences.) How central was this tactic to your approach, if you're willing to comment?
