Great but needs a settings option

I recently downloaded this game and i love it, Ive been playing it any chance i get. Ive even been recommending it a lot to my friends. The only with the game that i always have is that there isnt a settings option in the game. I always have my earphones on listening to music and Id really like to be able to mute the sound of the game so i can hear only my music. Please fix this
