Obviously the character and environment detail is better on the 3DS, but the N64 versions murky lighting and less contrasting color palette gave the game a very awesome and mysterious feel. Nevertheless I'm glad they remade it. I don't know why I don't already have it for my 3DS.
I don't remember having a hard time with the water temple, and I don't consider myself to be the greatest gamer either. maybe I just got that one, hard to locate, piece to the dungeon puzzle that can easily be overlooked?
Slaya49fan could be a "him" I suppose.
