Experimenting with spells, the old magician did such a thing that he himself did not understand how he ended up in a completely different world far from his tower. He looked around and realized that this world is not easy, to get out of it, you have to go through many portal doors. His ability to control objects, but not all, but only the gray stone blocks on which the arrows are drawn, is useful here. They mean which way you can move the block to use it to build a bridge. On it you can move and dive into the portal to a new level of the game WIZ.
