Nice! Much more rewarding to fool the AI now - or shocking when pulling a Wile E. Coyote move!
One gimmick still, I couldn't really comprehend why the game ends a seemingly random number of moves before the whole field is revealed. Maybe tries to deduct that one side can't win, but I think how cursed the endgame may get with false-flags and 50-50 situations, it might not be accurate. Would leave it out entirely, let the game conclude as normal, the last moves are about the most interesting.
Not really a fair game, rather a novelty, while the endgame is very interesting, the randomness of the beginning (lucky big reveals) isn't that great. If in for the game, not necessarily for the win, it is fun with its uniqueness (be bold, seek out for those tiles which may have a good chance). Against the AI, it is fun though to turn it back from a lucky opening.
Maybe cap reveals at 10 points by default? So equal to the mine penalty, that is, each reveal giving an advantage of one misstep.
