Meanwhile, to actually answer the question asked... am I to understand that you just got the Roc's Feather? After that, go in the tall skinny house north of where you entered the town.
I just got this game after some debate on whether or not to do so. I tell you, it is worth it. Unlike any other Zelda out there (except Four Swords :P) but still a great little romp. Lots of throwbacks to LttP, which is awesome. Haven't had a chance to check out the multiplayer, but the single player is pretty worthwhile. I can see that multi would be aweome.
