Thanks. I appreciate the comment. I never played SMB, but now that I look at it I can see the reference! I grew up playing games like Marble Madness though, and I had more than one Labyrinth board in my home. My kids had Perplexus growing up, so I've always loved the concept of getting a marble through a maze. :-)
