This game is a blast, pun intended.
It took me a moment to figure out that it was actually a sokoban style game because it wasn't clear I was the dark mine pushing the light ones. But once that clicked, I was in. Maybe an extra line of tutorial like, "you're the black mine, you can push other mines into place" would help?
I'm still not sure my brain truly understands how to arrive at a solution, but your puzzle design allowed for straightforward deductions to help the solution to arrive eventually!
Super well done, I'm very happy with this. And the retro presentation are incredible, even if the minesweeper I grew up with never had music :P
