-Minesweeper 'chording' feature is now implemented:
Click on a numbered square. If the number of adjacent flags matches the number on the square, a click is triggered on all other adjacent squares. It's a handy shortcut, but be careful all your flags are placed correctly!
-The game now begins in windowed mode instead of full-screen. Windowed mode and full-screen can be easily toggled by pressing F11 (or Fn + F11 on some keyboards). There is also a small text label in the options menu to remind players of this hotkey.
