I guess, I think I'll keep it though as it is a good way to resolve 50/50 situaltions, you can flag both of the tiles and will then win even though a non mine tile is flagged, the only change is that your score is lower.
Yeah, I'm going to add a score that is calculated by doing { score = (flaggedMines - wronglyMarkedTiles) / totalMines * maxScore }, that will punish wrongly marked tiles but still make a 50/50 work.
