Crystal Mines for Nintendo (NES)
Confront 100 monstrous worlds plagued by avalanches, lava flows and mud
slides. Your object is to mine the valuable "Starla" Crystals by
learning to use the ingenious devices in the mines. You can blast your
enemies with energy balls and explosive or crush them by setting off
avalanches. But watch out for unexpected chain explosions, for they can
easily blow your robot to bits!
