Query: Harder than it looks

Despite what the editor's review above states this is a challenging puzzle. While it has fewer possible configurations than a traditional Rubik's Cube, its odd shape and the fact that some of the pieces are very similar in shape make it more difficult to solve that you would expect. Also, it does not move as smoothly as the normal cube, so you have to be more careful to line up the pieces properly after each twist in order to make your next move.
