Adding death screen into the minefield

After we had manage to transfer alex's finished minefield level into the current version of the game. I Indeed to set up a simple restart/death script for when the player walks into a mine, what i made was canvas which spawns after the players sets off one of the mines and pauses the game, at this point the player can choose to either restart the minefield level again or choose to reset the game by going back to the main menu.
