This game was WAY better than I expected. I saw that it got good reviews, but I was reluctant to spend my time with a Zelda game because I usually get bored and don't finish them. This never happened with this game.
The story is really well-written and very interesting, the controls and combat are fluid as I would expect with a Zelda game, there is a wide range of items you can acquire, and the dungeons are fun, well-crafted, and have the exact right amount of challenge (for me anyways). Some avid Zelda players may find them boring or too easy, but for me, they weren't too hard, but not too easy.
I beat this game in probably about 15-20 hours over the span of a week, so it's relatively short, but unlocking 'hero' mode once you beat it on 'normal' provides some replayability if you're considering buying the game. I did not run through hero mode, but I'm definitely considering buying it because it was so great.
This is certainly the best game I've played on my 3DS so far and is worth at least a rent for any Zelda fan. There are really no flaws that I saw in this game and being the best game on the 3DS that I've played, I give it a perfect 10.
All in all, it is a fairly short game, but you will love every minute that you're playing and is certainly worth the time that you spend on it.
