It's very minesweeper! I had to remember how to play that game xD
I think it's in desperate need of QOL though cause like, having to repeatedly go back to reset the puzzle on a large map like this feels like a chore, and your character moves too slow by default. I think a better way to add challenge to this other than having a "the fields lie to you" right on the second puzzle is to have multiple maps of varying sizes, kind of like the easier settings on default minesweeper that gradually progress to being more complex.
