MEAN 0 (Level 3) INSIDE 3D CUBE
Each hieroglyph is a layer of the maze. First layer is on the up and the left of the map and last one is of course on the right and down. But be careful, the ball at the begining is not on the up and on the left of the first hieroglyph! A small black square matches with a hole in the layer of maze. It allows the ball to reach a lower level.
