I'm having issues muting all sound and music completely from the game. I can only click the bar down to the one block setting, and I can still hear clicks and slight. As I'm watching a movie on the other monitor, this is highly annoying, and I can't mute my browser as it is the source for the movie.
I couldn't stomach a whole 10 levels of this. Classic idea, nicely executed, but the levels go on a bit long and i got way too repetitive by stage 6. 4/5.
