I like the concept, and it's kinda fun

But the fact that hitting a mine just means that I have to undo my last move (for free btw, I think) just kinda trivialises the whole act of hitting a mine, especially since it just stays in the same place, so I can just flag the tile I hit the mine in. That's what's stopping this from getting 5 stars

But I'm way too cool to exploit an issue like that, so I actually used logic (and it was fun)
