It breaks!

What we are doing

Landing on a trap breaks it: no bounce, and the broken platform falls away. The player keeps falling, maybe onto a real platform below.

```js
if (p.broken) p.y += 5 // a broken platform falls away

  if (!p.broken && over && oldBottom <= p.y && bottom >= p.y) {
    if (p.kind === 'breaking') {
      p.broken = true
      continue
    }
```

What it means

• A broken platform can no longer catch anyone (!p.broken).
• Landing on a trap marks it broken and continues to the next platform instead of bouncing.
• Every frame a broken platform drops 5 pixels until it leaves the screen.

Your turn

1. In the platforms loop of update, write the falling line first.
2. In the landing check, add !p.broken && and the trap block.
