Castle EXELENT

Originally released by ASCII in 1985, Castle Excellent is a notoriously difficult action-puzzle game set within a vast castle comprising 100 rooms. Created by "Marchen Maker," the game demands precise jumping mechanics and sharp logical thinking, which captivated PC-8801 users of the time. Its challenging design forces players to strategize the efficient use of limited keys and items, where a single mistake or wrong move can lead to an impossible situation, maintaining its allure as a formidable test of skill even today.

The goal of the game is to rescue Princess Margarita, who has been kidnapped by the Demon King Mephisto and imprisoned within Glocken Castle to serve as a singing doll. Prince Raphael of a neighboring kingdom steps into the vast, trap-filled castle to save both the princess and two fairies held captive within. Players must navigate a complex labyrinth of 100 rooms, unraveling numerous intricate puzzles as they push toward the deep interior where the princess awaits.
