Only its Boss Fights were easy, the Puzzles were still the hardest of any other Zelda game. even the mini bosses were tougher than the actual boss battles. Shigeru wanted more puzzle solving in this game and there's a crap-load on TP. It stimulates you mentally.
I think its hard for people that havnt played a zelda game befor or just dont play them as much. ya the zelda team people are focusing more on getting people that havnt played a zelda game so they can get use to it than to challenge us zelda fans......
