Don't make it any easier. I love tough quests. But if you have to, then make 2, or even 3 different versions (easy, normal, hard) if you like.

Easier way of doing a easy/hard mode is something that Blonde suggested to me for a while ago. If you have some kind of a title screen, it could say on a screen "easy" and "normal/hard" for example. If you choose the easy mode, then put Link going through a screen under a layer on a conveyor collecting some upgrades to make the game easier. That's just a suggestion.
