I'm on the first level. I got out of the cave, went to the bottom of the hill and went around it to the right. Eventually I came to an opening with all the bent bars at the mouth. I squeezed through, mistakenly thinking I hadn't been here before. I quickly realized two things...
A. I HAD been there before and
B. I can't get out because I caused the cave-in earlier. You can't get back through the bent bars and the second opening, where the guard is is too high.
Boy, nothing quite like a ridiculous predicament like this to shatter all illusion of reality.
