Castle of Deceit is an unlicensed NES platformer developed by Bunch Games. You play as Cebo, a young wizard trapped in a mystical castle where the lines between reality and illusion are blurred. Your goal is to recover the stolen Rune Stone by navigating treacherous levels filled with deadly creatures and environmental hazards. Known for its steep difficulty curve and lack of a save system, the game demands perfection from the player. Armed only with a single magic spell, you must master the game's mechanics to survive. It is a challenging relic for collectors of obscure 8-bit software and those who enjoy testing their patience with high-difficulty retro titles.
