Hell Diggers

Help these miners or diggers to get back their gold. The hell in the name of the game has two meaning. The guy got really deep and they have bubbling lava under their feet. The second is description of the difficulty because it's really hell. Use your workers to drill, move and don't let them to fall down. Just one mistake can mean restart of the level. You have to mostly combine all the three guys. It's good logic game but, oh my, the difficulty.
