I know this game hasn't been updated in two years, but I really like the idea here and I want to give my thoughts.
I think if I accidentally click on a mine that is not currently indicated by any circles from probes, the mine should be moved to another location instead of instantly losing. It's okay if there's already a probe down because I know clicking anywhere on the circle is a risk of exploding, but when I click in the middle of nowhere to put down a probe and randomly die it's extremely not cool.
I also don't understand the lose conditions in this game. Sometimes when I try to validate an incorrect flag it flashes red and I get to keep playing, and sometimes it ends the game. As far as I can tell it has nothing to do with how many probes I have used, or how many failed attempts I have made. The exact losing conditions should be outlined in the instructions.
