Castle Master

Long ago, the Magister created the world and all its creatures. One creature rebelled against his control, man. The Magister watched with bemusement as man increased in number before deciding to sleep beneath a hill in England. A castle was built upon the hill, called Castle Eternity. Eventually, in medieval times, man awoke the Magister from his slumber, but his power had seeped into the land. So he bade his time until the day of a great feast, held by your father, the king. There the Magister turned the castle's inhabitants into all manners of ghoul and beast, but thankfully you and your sibling were outside the castle at the time.

Gameplay combines action and puzzle-solving across four primary towers with three levels each. Doors must be opened using one of the ten included keys. These are unmarked, as are the various potions - making it a challenge to know which keys open which doors, and which potions are beneficial.

Contact with ghouls drains your energy, as does falling too far (there are narrow pathways to navigate). Eating cheese can replenish your energy levels. Movement and aiming are controlled separately.
