Add new functionality to this java game on netbeans

This is the code in java on netbeans of the game minisweeper well now i need you to implement in the same game, a new play mode which consists in the following rules: * it has now two type of bombs: a)the letal ones and b) the light ones You need to adapt the game to this new logic,,, and also modify the interface according this new functionality every board according to the difficulty: EASY MEDIUM OR HARD has an specific ammount of letal bombs and light bombs if u click a letal bomb happens you must creat a masive destruction effect in the interface and u loose inmediately but if click a light bomb you just loose one life the player has three lifes in total that should appear and be visible in the interfave with a heart logo representing each life once u lose one life it must dissapear from the interface and if u hit a light bomb doest have to expose all the remaoning bombs that just happens with the letal ones, if u click a letal bomb u loose the game and also u have a custom mode if you dont want the typical EASY, MEDIUM, HARD in the beggining of the game when the player inputs the size of the board and the ammount of letal bombs and light bombs it want to play with. Now i give you the information about how many of each type of bombs every mode has: EASY: (10x10) has 2 letal bombs and 8 light bombs MEDIUM: (16x16)has 10 letal bombs and 41 light bombs HARD: (30x16) has 38 letal bombs and 153 light bombs PD: the game is already well implemented and running you just need to add this new play mode
