I already played, rated, and left a comment on your game three days ago. However, I just tried again and beat expert in 8 minutes. Admittedly, I have played hundreds of hours of minesweeper. :)
Difficulty rating: ★★☆☆☆ - 2/5
Ohh sry for double posting. But glad u liked it. You think it needs to be harder?
I just tried playing a normal minesweeper at expert level, and it took me 6 minutes. So, I think the difficulty level of your game is just fine.
