Good idea, I had fun solving these. Took me some time to figure out level 2.
I think most levels were just normal Minesweeper though? Would be cool if they all (except the first maybe) had some modifiers.
Level 2 to 5 have some kind of modifier but the one in Level 2 is the most interesting one I'd say. I'll try to find better ideas for future version ! Thanks for the feedback!
