Want to tinker with this game? Here are a few ideas

• Do nothing when the user tries to move to the direction the snake is coming from instead of failing
• Change the snake's speed
• Add a key to restart the game
• Keep score and report to the user
• Add obstacles
• Play a sound when the snake eats the apple
• Report game over to the game window instead of to the console
