Hello Minesweeper fans, I got a lot of nice things here for you, thanks for feedback and suggestion ;)

• More music has been added to the game!

• Added multiple sound effect variation, I know some of you don't like the default sounds, now you can try out a few different ones.

• 3 New Classy levels!

• Added a credits screen, where you also can find the music list.

• Some minor bug fixes.
