Mean phantom

The 3d labyrinth where you play blind. You have to bring the ball from the top of the cube to the bottom. But when you free the ball, it disapears into darkness. Your only clues are the sound of the ball and the map of each level which is engraved on the cube. But don’t believe it’s easy to overcome darkness. You will have to go down, up, down, up, down… This cube contains a second ball (the phantom, in a forgotten walled living room …). No easy cube here. If this is your first experience with the cube, you might want to try an easier one!
