I'd like to have the option to show "remaining" mines. I've played https://pwmarcz.pl/kaboom/ enough in "countdown mode" (i.e. where the numbers are the number of hidden mines) that I can't adjust to this....
Although the number I show is actually a bit sneaky, as I subtract the number of flags placed to the total number of mines. So if you were to place more flags than mines, you'd see a negative number. (which I realise as I type that your version is similar, as the number can also go above the total).
I'm more leaning toward not adding more options, as I'd like to keep the game as simple as possible, but nevertheless I'll have a think, it might be worth it.
