I think that the best thing about this game was the graphics. They were probably the best 2D graphics I've seen in most games, they simply blew me away. Other than that, just mainly the fun it is to be controlling more than one Link, and the twists that that feature has on some of the puzzles in the game. Also, because you had four Links to control, and four more sword to swing, there were points where you had to fight literally hundreds of enemies at once, and it was awesome to plow through them. I also enjoyed the multiplayer in this game. It's not often that Zelda has multiplayer, and I believe it has only been a part of FS, FSA, and PH. I never really often played the main story of FSA with multiple players, but I've spent hours fighting against my brother in multiplayer. It's a lot of fun, I think, and I remember it being rather addicting.
As for dislike, there weren't really a bunch of little things that annoyed me, but overall I disliked that the game seemed, too, say, repetitive. A lot of the puzzles were the same, and the different levels didn't have too much variation, and they all had the same goal, get to the end with 2,000 rupees. Also, I found the final boss fight irritating. It wasn't hard or anything, but it took forever! Too much of doing the same thing over and over again until the fight was finally to the part with Zelda, and the balls of light, and eventually the end of the fight. I'd rather be disappointed when a fight ends because it was fun, and didn't like that I wasn't fighting anymore, than being glad when it was over because I didn't have much fun and wanted it to be over.
Overall, there was more good than bad about this game. But there's something about every Zelda game that irritates me, and I think that this game wasn't as good as most other Zelda games.
