Ouch, that's harsh. What difficulty? Thanks for playing btw!
Intermediate. Suggestion: maybe add a mine count?
How would that help with 50/50 situations, or is it just meant as a nice tool to see your progress? (I'm actually already adding it, and some settings + audio to the game in the next update)
It was something like this (P = flag, [] = unopened cell) :
2 P 4 P
[][][][]
There are 2 possibilities for this, one that requires 2 mines, and one that requires 3.
