In a 2020 interview about Luigi's Mansion 3, the game's lead producer Kensuke Tanabe (who was also the scenerio writer for A Link to the Past) compared a shift during the game's development to an early idea that was scrapped during A Link to the Past's development, revealing that the game originally had multiple parallel worlds but it had to be cut down to just two—those being the worlds of Light and Dark.

"When that happens, I try not to cling to that initial idea too much. For example, this is when I was working on The Legend of Zelda: A Link to the Past. At first, we were thinking about structuring the game with numerous parallel worlds. However, in order to establish the gameplay in the end, we decided that it would be better to narrow it down to two worlds: Light and Dark. I think game development involves much work where you never know unless you actually test it out."
