Ularn is a variant of Larn, a game from the era of Rogue. Your daughter has contracted a strange disease and you must try to save her. Seek out the great magician Polinneaus in the caverns of Ularn.
The first level is plagued by lemmings. Do not attempt to fight them in the open. Pull them to a long narrow hallway to whittle them down. Very poor game design, but less of an annoyance after you gain some levels.
