I have completed my minesweeper game using Tkinter and would like to know ways to improve. I also have a question for extra features: does anybody know a way to have an opening start, like Google minesweeper does where it breaks open a bunch of squares?
I'm accepting all comments.
Please criticize: readability comments and performance comments accepted.
