Separate the parts and join them back to starting position.
Have you ever heard of the Mobius strip?
It is a complex surface where the front and back are indistinguishable. In this puzzle, obstacles are placed on the surface and block the way, just like a maze.
As you move forward, the front becomes the back and vice versa, leaving you perplexed. The theme of the puzzle is the strip.
