On level five, the exit is quite far away from the reactor, and the path to it involves several turns. Rather than memorizing these turns, this demo shows how I used markers like a trail of bread crumbs that show me the way out. (Being a boater, I like to think of them as "aids to navigation." :-)

At the start of the demo, I have already dropped the markers and am about to blow the reactor. Once I do so, I simply follow the markers out, turning in the direction indicated by the marker text. Note that afterburner is not required to make it in time (although it does provide a safety margin :-).
