Maze generator using LAMBDA

Was testing the limits of LAMBDA, dynamic arrays, and recursion, and created a maze generator using a randomized Kruskal algorithm. You only need to enter a height and width, and Excel takes care of the rest! I had to limit the maze size to 10x10 due to some apparent recursion limits that LAMBDA applies. If anyone knows how to raise these limits, I'd love to hear about it!

Enjoy and Happy New Year!
