Title: An interesting twist on puzzles
Review: Solving this puzzle requires the solver be able to hold and understand two objects in their mind. Past that first challenge, the rest becomes easy. It's interesting in that it's the only puzzle I've seen that explodes itself between two shapes. Fortunately, or unfortunately, depending on your puzzling abilities, the two tetrahedrons it switches between are very simple to solve. To me, it is only a little more difficult than a fifteen puzzle or the KO labrynth, but the novelty of solving two shapes at once hasn't worn off yet
