An extremely good follow-up but not without flaws.
I know quite a few people who refused to play LoZ: Wind Waker because of the departure from the Ocarina/Majora's Mask-style graphics. I, however, loved the Wind Waker's art style. Therefore, seeing it almost perfectly recreated on the DS, I was in awe of the beauty of the game. And then on top of that, there were loads of clever uses of the touch screen with the gadgets and great puzzles and mini-games. But this does bring me to one of the game's issues...
The control scheme. I wasn't completely comfortable with using the touch screen exclusively. There were issues that arose like the rolling dodge not working exactly when I wanted it to or running around when I wanted to slash an enemy. These problems aren't enough to drop the score any, but one thing that did get irritating was having my own hand get in the way of the screen while playing. Several times I would miss something because my hand was obscuring a creature or point of interest. Another minor point was that some puzzles had really vague clues, but nothing seemed to get overly difficult to the point of impassable IF you made sure to read all the clues and take copious notes.
Overall, a fantastic handheld adventure with plenty of extra side quests to keep the perfectionists busy for a while, but for those of us who just want to enjoy the main story it's got plenty to offer as well. A must for all Zelda fans and a great adventure for just about anyone looking for a bit of a challenge.
