I want to change this menu so I can use my own background in .png 800x532 and
add 4 buttons 175x40 in .png one that initiates a .py called Guns.pyone that
links you to a highscores.txt file thats read onlyone that links you to another
.png file with the ability to go back to the main menuOne that terminates the
window
