Interesting game! I also didn't know how to play minesweeper going into this, but I was able to learn it through playing this game. I think that, in addition to music, one improvement to the atmosphere of the game would be a background that fits with the theme (is it just me or is the skysphere in this rotated about 45 degrees?). I did a project a while back with a city in the same vibe as this game, all dark shapes and neon lights and strips running here and there, and I think something like that would serve as an excellent backdrop for this game. All in all, good job!
