The puzzle also locks away a copy of the official Stickman Book (edited by Matt Dawson) with 50 pages of color pictures, descriptions, and background on every Stickman puzzle (past and future), as well as a full biography of Robert Yarger. Quite an interesting read for any puzzle enthusiast!
Despite being visible, the mechanism doesn't give up its secrets immediately: you need to find the first move before you can see it in action! Fortunately, after a bit of fiddling I was able to get things under way nicely. Even once I had things moving, it wasn't entirely clear what was going on, but a bit more investigation helped me figure things out. I think that's one thing I really liked about this puzzle: you gradually start to understand it as you play around with it. Much more satisfying than a puzzle that you end up whacking and shaking until you stumble upon the solution!
Overall, I really enjoyed this puzzle: I love Robert's more mechanical works with visible gears/mechanics, and this one really delivered on this front. As a puzzle, it was quite enjoyable, though not overly difficult. I think it took me about 30 minutes to solve it, though it could easily take an hour or two, which feels just about right. No real downsides to this one except maybe the price: it was a bit steep but definitely reasonable considering the absurd amount of labor involved! It is masterfully designed and crafted, and a fun puzzle to boot! I'm already looking forward to seeing what Robert will come up with next!
