In Light & Dark you control a ship in space and your escape pod engines are out of power... but your laser still works.
Navigate the world using your laser to collect crystals to upgrade up your ship. Unlock more levels and discover unique enemies. Bosses are found at levels 25, 50, 75 and 100. Go from cautiously mining crystals to searching for treasure chests to blowing up enemies to running for your life.
Very challenging game that could take several hours per completion.
