Great Game! Got through episode 2 with highest difficulty after 5 attempts at the final boss, neat mechanic=)
Also want to make a suggestion, when I played I got two problems:
1. In the minesweeper version I usually play there is a mechanic called an "accordion", with it, if you, for example, click on the "3" with a flag mode activated where there is only 3 closed squares, it automatically places flags on them, saves a lot of time;
2. Maybe this is intentional, but for me it was kinda difficult to differentiate real squares from that of background, too little contrast for grid
