Zelda series director Eiji Aonuma spoke recently about the upcoming Link to the Past sequel for 3DS. As with the original game, players will shift between Light and Dark worlds. However, despite the classic top-down perspective, Aonuma said the game will be a “departure” from the usual Zelda fare. In particular, he stated that the staple of finding items to progressively open up the game world “certainly feels different from [the developer's] point of view.”
Additionally, Link will have the ability to jump into the walls as some kind of drawing, ala Phanton Ganon from Ocarina of Time. The game will also make some use of the 3DS’ 3D capabilities, although no further details were available.
