Quite good game.
However there are two main problems:
first the game is not very attractive graphically.
secondly when you start a microsoft game, you can not loose in the first click. that is not the case in your game.
To conclude, it is a good game except the graphism.
It would have been nice to allow the user to specify the size of the array to solve, or the mine density to allow an easier game.
As it is, the author is to be commended for a nicely implemented game. No problems that I found in a few test games. Good, readable help, and an H1 line. Good internal comments, good programming style.
