“We were told by Mr. Miyamoto that he felt there were a lot of users who finished the original without even noticing all the hidden events scattered around the town,” Aonuma said to the magazine. “He said that he wanted us to make sure users were more aware of them this time around.”
The Bomber’s Notebook is an item given to Link during the course of the game and helps keep track of the game’s quests. In the 3DS version of Majora’s Mask, Aonuma says, it will use both screens and “act more like an electronic notebook that leads players to these hidden events”.
The Legend of Zelda: Majora’s Mask 3D will be released this Spring.
