Well I'd like to assume this includes being able to mute the BGM on top of the 'all SFX off' option.

All they need to do is add the wind to the current SFX mute option. Problem solved.

I found it hilarious in the letter when it said "even more sound options for you!". It seemed kind of sarcastic, like they can't appreciate the fact sometimes people want to mute the entire game.
