Completed all 8 levels. I know the concept will be good if it has minesweeper in it :)
Puzzle design here is kinda mixed to be honest, some levels had too many tiles to process so I just randomly pressed every key until it works. Level 4 and 8 are examples of this. But other levels didn't have too many tiles to process, so I could actually think about the positions of the mines. Those levels were much more satisfying to beat, such as level 5,6, and 7.
Overall, it was an enjoyable experience. Well done!
