Minesweeper?
I started off playing thinking "meh it's gunna be another minesweeper" however this isn't minesweeper, totally different objective, people who are trying to play this as minesweeper are doing it wrong, you're meant to use the minesweeper "scoring" of mines to clear a path from one part to another.
That being said, there is room for improvement; I would suggest making the exit move each level, north west to south east repeatedly doesnt actually work in a labarinth for more than about 3 floors, you could also add in a money system, and the ability to buy lives, or a quick peek at the squares.
Other than that it's a good game wth good potential
