Games do not progress past level 2

The Simon game does not progress past level 2

This is due to setting userClickedPattern = [ ] in the nextSequence() function.

The userClickedPattern.length does not match gamePattern.length in the if statement inside the checkAnswer() function after level 2, thereby triggering the else statement containing the game over screen.

This bug is easily fixed by removing userClickedPattern = [ ] from the nextSequence() function and placing it inside the startOver() function.
