Movement and apples

     I have made it so that after you start the game (press A) the
snake will start moving up. You can change the direction with the
direction keys and the snake will wrap around the screen instead of
going off screen.
     I also made it so that if there is no apple on the screen the game
will spawn one in a random location which you can collect.
     Right now collecting apples does nothing more than beeping and I
don’t have a scoring system or a way to make the game get more
challenging.
