Last week the level icons update arrived in my game, and in addition to new icons and backgrounds, hard levels now have their own music. And it's so good!
I always play with the sound on, so I've noticed that this new music has some bugs:
-When I lose a level and want to try again or play another hard level, the music doesn't play and it can only be fixed by reopening the game.
-When I run out of moves, after getting more and winning the level, when I play another hard level the "Out of moves" loop plays instead of the level music.
