Just beat this game yesterday. It was great. A great entry in the series, about on par with the recent console games. Definitely the best handheld Zelda since Link's Awakening.

Spoilers below!

It wasn't perfect, though. I found the level designs were a bit simplistic and lacked sufficient puzzle challenge. There was some beauty in that but I would have liked more. The game was actually very easy. I was scared of dying and losing my items with the rental system but I ended up not dying once, even in the Treacherous Tower.

It was quite mesmerizing once the rental shop became available and the whole world opened up to me. I also liked that you get useful items like the Power Glove and Pegasus Boots just by exploring and talking to people. There's a flaw in this system though, particularly with the Lorule dungeouns. By making the whole game an open world you really have to scale down the difficulty of the dungeons so that Link can tackle them in any order. I didn't notice much change in difficulty in any of the 7 Lorule areas other than the Ice Cavern. So once I had close to max hearts, blue mail, and level 3 or 4 sword all the rest of them were a breeze.

My other gripe comes from the final boss. I really don't like that they used the 'hit the ball of energy back at Ganon' tactic again. It's been done too many times. The final battle other than the painting stuff (which was fun) was pretty vanilla and unoriginal. I did really like how the final dungeon had some large puzzle rooms that required you to use your item sillz but I wish there were more of them, like one for every item. Tornado Rod and Sand Rod needed more love in this game.

The painting mechanic was awesome and pefectly incorporated into the game. That and the nostalgia from returning to the LttP word were the best parts of the game.
