Overall, a solid twist on minesweeper.
Some gameplay feedback: I think not having the ability to 'flag' mines is a bit exhausting to keep track of. I also think the mouse should just move horizontally/vertically to the tile you click on as you're solving it (always preferring to use safe/previously solved regions when possible) instead of building a path after solving the minesweeper field. Just feels like extra work after already solving the puzzle. Or maybe forgo clicking on the screen and use WASD keys to move the mouse?
