`spawn` - точка спавна.
При указании точки спавна, указывать шестой параметр `World` не имеет смысла,
т.к. `SimpleWorld` всё равно перезапишет этот параметр.
`layersBlock` - слои блоков.
В качестве значения указывается спиток строк, каждая из которых описывает слой блоков.
Формат строк такой: `кол-во_слоёв;тип_блока`. Порядок строк такой: сверху нижние слои, а снизу - верхние.
