Enemies will walk along a winding road. Listing every road tile by hand would be long and easy to get wrong; we list
only the corners, as [column, row], and let the code fill in the straight lines between them later.
```js
// The road, as corners in tiles. It starts off the left edge and ends off the right edge.
const PATH = [
[-1, 1],
[3, 1],
[3, 6],
[7, 6],
[7, 2],
[10, 2],
[10, 7],
[12, 7],
]
```
What it means
PATH is an array of arrays; each corner is [column, row].
From one corner to the next, only one number changes: the road runs straight across or straight down or up.
