Great game and I was surprised by the amount of polish (even had settings for dark mode!)
I'm not a huge fan of the original minesweeper because of having to guess sometimes, but since you went with the hex shapes, you can take a look at Hexcells or Hexceed for examples of similar games that don't require any guessing.
Also, I didn't see a setting to invert the controls, which I think would be a nice accessibility feature. I often found myself clicking the opposite button I was supposed to, but maybe that's just a problem with me!
