To many buttons/pads in use?

We can change the buttons used for the game to ["A","B","C","D"], and not use "Back" or "Enter". We can use the spare buttons to stop or reset the game. Or we can use them to change difficulty.

Also, using 4 buttons instead of 6, for the game itself, makes it more manageable to play.
