Neat... but I'm missing the left+right click, in the Windows Minesweeper, say you have a square with 4, and you've marked 4 squares around it as bombs, you can left+right click on the 4-square and uncover all the unmarked squares around it, instead of going one by one.
Also "undo" is cool, but "lose 60s" seems backwards, considering one would get 60 seconds added to one's time.
