Fly again

What we are doing

After a landing or a crash, Space (or a tap) starts a new flight over new hills. The decision lives in one function, next().

```js
  if (event.key === ' ') next()

function next() {
  if (state !== 'flying') reset()
}

canvas.addEventListener('pointerdown', (event) => {
  if (state !== 'flying') {
    next()
    return
  }
```

What it means

• Space calls next(); next starts a new flight only when not flying.
• A tap after the flight calls next() too, and return stops it from also holding a steering key.

Your turn

1. In the keydown listener, add if (event.key === ' ') next() as its last line.
2. Above the // Touch: ... comment, write next, followed by an empty line.
3. At the top of the pointerdown listener, write the if (state !== 'flying') block.
