[Death by Mirrors]

It has been raining all day, but once you pass the muddy field, the sun comes out. Soon after a magnificent rainbow starts to form and is leading directly into the maze. You can't see where it ends, at least not yet. It just seems to vanish somewhere between the corn stalks. So you look around for your options instead. Apparently you could go straight ahead, or you could also take a turn to the left.

Go straight, or go left?
