Bruno, I think I saw you mention that Twilight Princess was your first Zelda in a long while, if ever. You may want to take a break and try to play N64's Ocarina of Time for a bit. The controls are simpler yet I'll bet the concepts are the same. This exercise may give you some practice with the camera (UP not always being UP, etc). After a short time, you'll know to move the stick in the direction Link is facing, no matter where the camera is.

I wonder if in the vastness of the Internet, there is someone who will take your saved game, get you past the trouble spot, and send the save back to you. That is, if you can download the save game to a computer or send it via the Opera browser. Now THAT'D be a good use for internal browsers.
