This was my first experiment with coordinate motion moves in a Barcode Burr style puzzle. It's also a rare example where any maze path has a loop in it. My original design intent was to have something to include in the Barcode Burr Master Set which gave customers a small taste of what could be possible with coordinate motion, yet once I developed the GreenCode and CrossCode series of puzzles, my fondness for this one waned to the point that I'd prefer to include the whole GreenCode series in a Master Set rather than this one.
