Zelda: Sword of Hylia

From Zelda Fanon Wiki

Sword of Hylia is another fangame that takes place in a Time of Darkness. A dark Brittonok, named Ganon has Taken over Hyrule, and left the Rulers, Link and Ideya, to die. As it seems the world is doomed, a prophecy is foretold that the heroes would soon return. Indeed, they did. They battled Ganon and managed to knock the foolish fiend off the tower, killing him.
