I really love the concept of this and gave it a good go but unfortunately Ii really didn't understand what I needed to do. I was filling the littlee squares with pieces up and eexpecte dthem to make individual towers because of the warning that towers much b complete to be placed by when I went to place the tower all my space pieces when with it as one big machine. I really couldn't grasp what I was aiming to make.
Great concept though.
