It adds a bit of story to the game and uses the tilesets in ways I'm sure the creators never imagined. It's also fiendishly difficult, requiring extremely precise walljumps, midair morphs, speedballs, and IBJs in several segments of the game.

hack I'm making of Ocarina of Time. Unfortunately, progress has stalled a bit due to real life taking up more of my time, but I'd be willing to share the two dungeons I have completed with those who are interested. </selfpromotion>
