In the game's files is an unused audio clip of Zelda warning the player that the disk may be dirty.
The reason why Zelda: The Wand of Gamelon and Link: The Faces of Evil use a side-scrolling perspective as opposed to a top-down view is that the former manager of the development team, Dale DeSharone, believed that Philips would not approve a top-down view of the games as it would not make use of the CD-i's capabilities.
There are two unused backgrounds in the data for the intro and ending cutscenes. The first one is a leftover from Link: the Faces of Evil and the second one is unique to the game.
The cartoonish cutscenes were outsourced to a small group of Russian animators; they were flown to the United States and drew the cutscenes in a small apartment for six months.
