I changed up the ending, the timer ends when the ultrahand animation goes away and you have a korok with a backpack suspended in air about to fall off the sky islands.

This is a speedrun where as soon as you gain control of Link in the room of awakening the speedrun starts. Then you have to go to a korok with a backpack and throw them off the sky islands. The speedrun ends as soon as the korok starts falling off the edge.

I would say the die% such as the cliff or drown I think that would be fun
