Goblin Mines

This room looks suspiciously unthreatening initially.  To see the hidden danger you need to step off the orange path.

Half of the time, the path is entirely safe to walk along.  For the other half, there are certain sections of the path where you don’t want to be.

The trick is to keep repeating to yourself, “Danger! Danger! Safe! Safe!” in time to the rhythm of the room.  When you’ve got the timing memorized, walk along the orange path from beginning to end, waiting for “safe” moments before walking along the dangerous sections.
