I like to listen to an audio book while playing a brain game. works fine until an ad. I've the sound turned off on the game so the book still plays in the back ground but the ads don't respect that. id hate to be playing this game while lying next to a partner at night. or on the train. I'm sure I can get an equally good game on my phone which doesn't block my audio book. I have to go back to the book and switch it back on every time. very annoying.
