the Substrate in the puzzle is a hint, when you save the puzzle and come out, then the substrate disappears and have to spend yet another hint at the next boot of the puzzle, if the puzzle is great we can several times to save and spend on one puzzle a few hints if it is not technically difficult , make, please , so that the substrate opens with a puzzle, if the player "bought".
