This is a cool concept, but there are some features from another minesweeper variant called mamano sweeper that might make this better.
The first those features being the ability to defuse a mine and see the number at the mine's location. I think that would increase visibility and prevent 50/50 situations from happening as often.
The second feature is that you could put multiple mines on the same tile, which would prevent mines from blocking off visibility of areas as often by bunching up the mines.
