Next level or new game

What we are doing

After a landing, Space goes to the next level and keeps the score. After a crash, the game starts over.

```js
// After a landing, the next level; after a crash, a new game.
function next() {
  if (state === 'landed') {
    level += 1
    startLevel()
  } else if (state === 'crashed') {
    reset()
  }
}

    ctx.fillText('Landed! Space: next level', canvas.width / 2, 140)

    ctx.fillText('Crashed. Space: new game', canvas.width / 2, 140)
```

What it means

• After a landing: one level up, then a new flight (the score stays).
• else if checks a second condition only when the first was false: after a crash, reset() starts a new game.
• While flying, neither is true and nothing happens.
