Great game, but mute doesn't work
The game itself is great. I bought the upgrade to to disable the ads ages ago, which was pretty cheap. The interface works pretty well and intuitive. My one issue is that even though the game is muted (using the in-game mute button on the main screen) it's still making some sort of typewriter noise when I start a level, even when I'm not touching anything. If the game would properly honor its own mute button I would rate it 5 stars, but making noise when muted is a BIG no-no for me.
