Another thing I really like about the game is the boss battle mode. Now, before anyone goes "ZOMG YOU CAN'T PUT A BOSS BATTLE MODE IN ZELDA!!!1!1!!", it's not what it sounds like. It's not really a mode, but a side-quest. Kinda. There's a house in Castle Town with a lady that looks strangely familiar, and inside there are three doors that lead to three different portals. These three portals take you to a place not unlike the Savage Labyrinth from TWW or the Cave of Ordeals from TP. You find yourself in a room full of enemies, defeat them all, and move onto the next room. But the difference is, in this one, after a few rooms full of normal enemies and minibosses, you actually fight a real boss again! The first door only goes up to the first boss, the second door goes up to the third boss, and I'm guessing the third door goes up to the fifth boss, maybe sixth. I haven't beat it yet, so I'm not sure. Oh, yeah, did I mention that there are no hearts for the entire challenge?
