The International Bauhaus Museum has just opened in Waukegan. In keeping with the latest ergonomic fad, visitors are required to alternate between visiting bigger and smaller galleries. You really want to visit the armchair exhibit. Can you find your way there?
 
You cannot move to a gallery of equal size, and you may not enter a courtyard.
 
 
This is a variation on Karl Scherer's A-maze games, which are also available on Zillions. This version exploits an interesting property of A-mazes: An efficient winning path may pass through the same space twice. A 'loop' arises, for example, when you enter a space from a bigger space, exit as required to a bigger space, and then return to the same space from a smaller space. Your exit from the space will now have to be to a smaller space. With proper planning, an A-maze can be constructed that requires loops for its successful completion.
 
 
You should extract the game preserving path names.
