Cryptmorrow
An original dungeon explorer for the Commodore 64. Sixteen rooms in four zones under the hill of Morrow, three keys and three seals, skeletons and bats, and the portal of the Moss Gate.





Under the hill of Morrow lies a crypt of sixteen rooms in four zones. The explorer walks it with a sword: three keys for three locked doors, treasures and potions, skeletons and bats, and three seals that open the portal of the Moss Gate. Out through the portal, the game is won.
