Material Mole

Help a hedgehog to deliver the mined gemstones into the stock without losing any stone or golden plaque. Move by arrows, up is moving forward, to break and move backwards press down. The hedgehog drives on terrain where he can decide which way he takes. The switches are switched by the spacebar. Watch for the stones on the ceilings of the tunnels. When something shines there press shift and the treasure is yours.
