I'm stuck on the island with the pyramid. I'm inside looking at
A wall of redstone lamps. I have 5 levers that I'm guessing are for a puzzle involving the lamps but I can't figure out what to do. I've tried various configurations that light all the lamps but I'm still stuck in the pyramid. And I can't get out because I fell down a hole to get in and the ladder's blocked, presumably until I finish the puzzle.
