Castlequest (known in Japan as Castle Excellent (キャッスルエクセレント, Kyassuru Ekuserento)) is a puzzle-action video game.

Additional versions followed in 1986 for the Family Computer and MSX, and was subsequently released in 1989 for the Nintendo Entertainment System in the United States by Nexoft Corporation (the American division of ASCII).

The player must also avoid touching enemies like Knights, Bishops, Wizards, Fire Spirits, Vikings and Phantom Flowers.

In the Family Computer and NES versions, each room is wider than the screen, so the display scrolls horizontally as the player moves.

[3] Gary Meredith of Game Players felt that despite starting with 50 lives, the lack of a save feature could make completing the NES version in one sitting frustrating and difficult.

The magazine also noted the lack of a continue feature, but said the room reset function in the sub-command menu was helpful.
