So, I've been slithering slowly eastward now for more than 15 minutes, reckoning that if I had made this game I would have put something there, far far away, for the one fool stubborn enough to keep plodding onward, and also in the knowledge that the more intelligent (any maybe even more honest) thing to do would be to just make it go on forever. Either way, fair play to you, I believe that I've been beaten.
