"Just received the Lego Maze in the mail today and couldn't wait to put it together. Threw the whole thing together in about 3 hours (including a light lunch). Overall I love the mechanics/inner mechanisms that make the maze work, it is pretty cool to see how the tilting action takes place. I LOVE the idea that it is insanely modifiable and that many people can submit ideas, build multiple levels, have different themes (I'm working on a star wars one), but there is one major problem. In 2 directions the maze is greatly hampered in its ability to tilt. Sometimes when you are in a corner of the maze, you can't tilt enough to actually get it moving, so I do fear my wish to make a 2 story maze will greatly be influenced on the directions in which I can tilt hard enough to get up a ramp. I believe it is fixable by using a straight piece rather than an L shaped piece with a shorter connector, but without a different sized connector I don't think I can fix it with the parts included. I'll have to cannibalize another set to fix it. The idea was great, the execution was a bit off, if I am able to make it work with the pieces included I'll submit an edit."
