Thank you very much :)
I did in fact work on the graphics a little bit (pictured below) but the version that I had to upload was before I made the change to the newer background.
Also with the boundary I initially wanted to have all of the tiles covered and for them to be "fill opened" like in the original minesweeper but after about a week of trying to get that to work I sadly couldn't. I might have another shot at it though at some point. In a few months I might come back to this project and try again as I love what I've done with it so far :)
