Ошибка В Игре Змейка

[rhino101]

Помогите найти ошибку. Игра змейка состоит из двух модулей (main, game), main не может найти объекты из game. Может можно объединить модули в один?

unit main;
Отсюда убрать

implementation
uses game;

Сюда дописать

interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, ExtCtrls, game;
