Show the lives

What we are doing

The lives go at the top right, one ▲ for each.

```js
ctx.textAlign = 'right'
ctx.fillText('▲'.repeat(Math.max(0, lives)), canvas.width - 12, 26)
```

What it means

• '▲'.repeat(3) is '▲▲▲'. Math.max(0, lives) never lets it go below 0.
• Right-aligned text ends at the point, 12 pixels from the right edge.

Your turn

In draw, under the score line, write the two lives lines.
