Minesweeper 4: Diagonal the Square Roots

A recreation of minesweeper? Yes, I decided it's finally time. Now with an explanation:
The goal is to click everything but the mines. Clicking a mine causes you to lose!
The numbers tell you how much mines are around it, including diagonals.
Pressing space places a flag on the tile. Flags are used to mark mines. Tiles with flags can't be clicked. To remove a flag, press space again.
Variation specific:
Diagonal mines are now worth the square root of 2 mines. Apart from that, it is identical to normal minesweeper.
