The first time I played it on the VC, I found it moderately challenging, since I'm rather pathetic at solving puzzles/riddles/etc.

One thing it definately is though, is annoying. Any time I come close to beating Ganon, I hit him and then go flying off the ledge, so I have to go back, restock on heath/potions/arrows, and try to beat him again. Oh well, I'll get him sooner or later.
