Missed notes

What we are doing

A note that slips past the line without being hit is a Miss. Each frame, any note not hit and more than GOOD frames late is marked, counted and announced in red.

```js
frame += 1
// A note that has gone past the window without being hit is a miss.
for (const n of notes) {
  if (!n.hit && frame - n.time > GOOD) {
    n.hit = true
    judged.miss += 1
    judge('Miss', '#f87171')
  }
}
```

What it means

• frame - n.time is how many frames late the note is. At exactly GOOD frames late it can still be hit, so it is only a miss one frame after that (>, not >=).
• Marking it hit = true means it is counted once and no longer drawn.

Your turn

In update, under frame += 1, write the comment and the loop.
