Stop the clock

What we are doing

Once the song is done, the clock stops and presses do nothing. The lights and the message may still fade out.

```js
function press(lane) {
  if (state !== 'playing') return

  if (feedback && --feedback.time === 0) feedback = null
  if (state !== 'playing') return
  frame += 1
```

What it means

• !== means "not equal": when the state is not 'playing', press and the rest of update stop right there.
• In update the guard comes after the lights and the message, so they still fade out.

Your turn

1. Write the guard as the first line of press.
2. In update, write it between the feedback line and frame += 1.
