The game is sometimes alternatively known by its development title, "Dizzy 4", with the Roman numeral IV visible at the top of the game screen, behind the player's score. A prequel, "Into Magicland", was released to promote the game and featured a new character that was never seen in any of the series games again. The game was widely acclaimed by critics across the platforms with scores typically in the 80-95% region. Criticism was leveled at its similarity to previous games in the series and the awkward inventory system. By November 1991 it was noted that the Dizzy games had sold more than half a million units across all platforms. A NES version titled Wonderland Dizzy was developed in 1993 and later released in October 2015.
