The Legend of Zelda series producer Eiji Aonuma and co-developers Grezzo had started the development of Majora's Mask 3D immediately after the release of Ocarina of Time 3D, in June 2011. The project itself, however, was put under wraps for the majority of its development, with Aonuma and others involved with its development neither confirming or denying the existence of the game, but rather, suggesting that a Majora's Mask remake was "not an impossibility", depending on interest and demand. Following the release of Ocarina of Time 3D, a fan campaign called "Operation Moonfall" was launched to prompt Nintendo and Grezzo to remake Majora's Mask for the 3DS, in vein of Ocarina of Time 3D. The campaign name is a reference to a similar fan-based movement, Operation Rainfall, set up to persuade Nintendo of America to release a trio of role-playing video games for the Wii. The petition reached 10,000 signatures within five days.[citation needed] In response to the feedback, Nintendo of America released a statement: "At the risk of dampening the excitement you feel, I must be clear that no official announcements have been made regarding a remake of The Legend of Zelda: Majora's Mask for the Nintendo 3DS. However, we like hearing what our consumers find important." In an interview with GamesRadar in November 2011, Aonuma acknowledged Operation Moonfall, and told fans that he hopes to respond to their request sometime in the future.
