Small Bug in Snakes Sample AssemblyScript Code
In the sample project ("snakes") on the WASM-4 website, there is a bug in the code written for moving the snake in Assembly script.  The code in the documentation reads:

`    update(): void {
        for (let i = this.body.length - 1; i > 0; i--) {
            unchecked(body[i].x = body[i - 1].x)
            unchecked(body[i].y = body[i - 1].y)
        }
    }`

This code is missing a "this" before "body" when the "x" and "y" values are updated.  The code should read:

`    update(): void {
        for (let i = this.body.length - 1; i > 0; i--) {
            unchecked(this.body[i].x = this.body[i - 1].x)
            unchecked(this.body[i].y = this.body[i - 1].y)
        }
    }`

Thanks!
