I love minesweeper and thought I was doing a great job clearing those levels until I submitted my score lol well at least I was able to complete a medium, I got lucky at the end and had a 50/50 chance of blowing up on the last 2 mines :)
In other words I love all the little things you did to make the gameplay enjoyable, from the right set of sounds, to the little animations, it's very well polished and would make a really fun mobile release.
Great job!
