Minesweeper left + right together mouse button action isn't implemented. Also, this version of minesweeper lets you lose on the first click. There is also no high score. For these reasons alone, I am very upset by this entire demo.
Yep, no one who used Windows 3.1 extensively would put up with losing at Minesweeper on the first click. MS was actually pretty nice about rearranging the map so that the first click would not be a losing move.
All it needs to do is move the flag you click on to the first free square starting at the upper-left. The cheat helped me see this in action, but I've forgotten how to activate it now. I'll have to look that up again to see if it's implemented in this version.
