Try again

What we are doing

After a crash, Space (or a tap) should bring back a fresh run. All the starting values move into a reset function, which runs at the start and again after every game over.

```js
let runner
let state // 'ready', 'running' or 'over'
let obstacles
let speed
let nextIn // frames until the next obstacle

function reset() {
  runner = { x: 50, y: GROUND - STAND_H, w: 40, h: STAND_H, vy: 0 }
  state = 'ready'
  obstacles = []
  speed = 6
  nextIn = 60
}

  if (state === 'over') {
    reset()
    return
  }

reset()
```

What it means

The variables are declared without values at the top; reset gives them their starting values.
After a game over, a jump resets instead of jumping (and the next jump starts the run).
reset() at the bottom sets up the first run.

Your turn

Replace the five variable lines with plain declarations and the reset function.
At the top of jump, write the game-over block.
Call reset() right above requestAnimationFrame(loop) at the bottom.
