I like how juicy this is! The music gives me the feeling that I'm playing at an arcade or a casino, which feels appropriate since the game is so random. My best score was 23.
A suggestion: it might be better to put the score values that you gain/lose (i.e., UI for +1, -3) directly where you click, so you know immediately how much you're gaining/losing without having to look at the corner of the screen. I didn't realize I was losing so many points to the bombs until I watched the score closely.
Overall very nice!
