PLEASE provide a music-only mute button so that we can disable the annoying repetitive music without turning off the sound effects. This is a standard feature in most games, and very irritating for the 1 in 10 that neglect it. You might think the music is cool when making the game, but try listening to it for 3 hours in a row!
It rarely take the time to give low ratings to game, because if I don't like the game I tend to quickly move on to the next. But I've given this one a well deserved 1 star - whilst the game could have been good, it is too full of obvious and annoying bugs which should have easily been spotted through even the briefest of testing sessions. This should never have been published until the developer actually had production quality code.
