The mute/unmute gets affected by typing in your name for the score. Game is fun, but the only problem is that it relies a LOT on how the bubbles start out.
Perhaps an option to choose between keyboard and mouse control before you begin? I was using keyboard control at first and accidentally brushed my mouse over the game window, causing it to follow the mouse. Beyond that, it's a good game. A bit more randomizing and more levels would improve it a lot though.
I don't know about him, but as for me, my connection prevents me from sending any info. I can't get badges, submit highscores, play multiplayer, etc. And honestly, this game was decent, but because of the hostility and denial of the maker I'm lowering my rating.
MUCH improved over the original. One thing I noticed though was that it seemed to go from super easy to decently hard (in the enemy's health that is) all of a sudden.
