It might not have a level editor of its own, but The Legend of Zelda: Echoes of Wisdom started with an idea that was a lot like Mario Maker. On Monday, Nintendo published part one of its “ Ask the Developer ” series with long-time Zelda producer Eiji Aonuma and game directors Tomomi Sano and Satoshi Terada.

According to Nintendo and Grezzo, there was once a version of The Legend of Zelda: Echoes of Wisdom that let you make your own dungeons.

The Legend of Zelda: Echoes of Wisdom started out as a dungeon creation game, it’s been revealed. In an Ask the Developer interview published on Nintendo ’s website, it’s also been confirmed for the first time that the Switch game was developed by long-time partner studio Grezzo.

It’s been almost a decade since we got the first Super Mario Maker on Wii U and 3DS, and fans have always wondered if Nintendo might give the level editor gameplay treatment to one of its other major franchises,

Echoes of Wisdom appears to have leaked in full a couple of days before its proper Nintendo Switch release date. Reports from YouTubers a few weeks ago claimed that a rom containing Zelda's first solo adventure was already making the rounds,

Echoes of Wisdom ends up at the center of a massive leak similar to the one that affected Tears of the Kingdom.

New details that have emerged online appear to confirm The Legend of Zelda: Echoes of Wisdom's development studio. Nintendo has kept this information under wraps -- but fans of the franchise have long suspected a familiar studio might be the one making the upcoming game.
