If you use ubuntu, You can mute the music with the pulse audio volume controller program. The thing is, You can mute just this flash game with it, So you can still watch youtube videos.
You do realize that your character has no gender as far as the game cares, right? Did you miss the lack of male pronouns? The general lack of references to gender? The store having women's clothing? Or were you under the impression that I was disallowing women, but 100% ok with transvestites? We're getting all Shakespearean up in this bitch.
I'm glad the game let's you chose a female avatar, But, Every icon is male, Most of the idle animated avatars are male, and most of the employees you can hire are male. Ugh, Annoying
