Minish cap! its just THE BEST 2D zelda game EVER (in my opinion), its very long (for a GBA game), interesting story, great gameplay, funny dialoge, awesome Bosses, some of the best sidequests in a zelda game, simple and challenging dungeons, a variety of sword techniques (excuse my english, i'm brazilian), funny characters, and most importantly, it gets better and better when you play it, because you get new itens, open new areas, fuse kingstones (a item that open areas, gives you rupees, etc), meet new characters, get lots of upgrades and explore the world!
