Hmmmm.....well I have played that game many times...sooo....let me just....
~Tackles Zelda fan~ I'm so glad I've found another one of my kind ;-;....more Zelda fans are needed lol
ANYWAYS! Alright so, you have small arms right? I would suggest a few things:
1. Use your wrist a lot for a tilting and make sharp motions with it to try and make it THINK you're using the sword
2. Make big motions with your arms, kinda like you're actually there
3. Be VERY dramatic with your moves, make them clean and clear
Hope this helped >.< I have long arms so I'm not too sure what to do! But make sure you keep that wii remote strap around your wrist, I've had a few remotes go flying because of it
