as their contact may only have been fleeting beforehand. In response to this, the team considered how to make the player care about Zelda and want to rescue her. Having the two characters as childhood friends served this purpose and cut down on extraneous plot elements. They continued to encourage the player by having Link only just miss her on her early travels across the Surface. Mischievous elements were also added to Zelda's personality by her pushing Link over a ledge: initially intended as a rule of three-style gag, it was cut down to two during development. The figure of Hylia was a new addition to the world's lore, although her existence was linked to Zelda, with the two being essentially the same character known under different names in subsequent ages. Groose, who acted as Link's rival, was introduced to make the story more interesting within the school setting.

The basic starting point for the art style was that it was a fantasy world. The final version was referred
