What we are doing

After a fall, Space starts a new climb. All the starting values move into reset, which runs at the start and after every game over.

```js
let player
let platforms
let cameraY // the world y shown at the top of the screen: the camera
let highest // world y of the highest platform so far
let state // 'playing' or 'over'

function reset() {
  player = { x: 180, y: START_Y - 40, w: 40, h: 40, vy: 0 }
  platforms = [{ x: 170, y: START_Y, w: 60, h: 12 }]
  cameraY = 0
  highest = START_Y
  state = 'playing'
  fillPlatforms()
}

  if (event.key === ' ' && state === 'over') reset()

reset()
```

What it means

The variables are declared without values at the top; reset sets them, and fills the screen with platforms.
The player starts standing on the first platform (START_Y - 40).
Space only restarts after a game over.

Your turn

Replace the five variable lines with plain declarations, and write reset under const keys = {}.
In keydown, add the Space line.
Replace fillPlatforms() at the bottom with reset().
