Suggestion for addition of Menu or Options to 2048

2048 puzzle game is a mini game that is very interesting and also improve the brain capacity to think. But the game can be improved in many ways.
Having main menu in a game or options is very important. In this 2048 made by tpcstld the game doesn't have a menu. The menu of an application is always at the beginning of the application. When you open the game you don't just go directly to the game the menu offers varieties of choices to either choose to play the game or change the settings or difficulty or check your highscore.
