In a 1991 commentary with the game's composer Nobuo Uematsu published in the FFIV Minimum Album Liner Notes, he stated that in early plans for the game, the team wanted to use the unreleased track "Rosa o Sukue! (Save Rosa!)" aka "Restless Moments" for a scene where you had to save Rosa within a time limit or a game over would occur; this scene would appear in the final game in the Tower of Zot without this song.
