All you need to change is in Game_Main where it says if (KEYDOWN(VK_ESCAPE). Instead of using SendMessage(), do something like this:

    if (KEYDOWN(VK_ESCAPE)){    PostQuitMessage(0);    return;}

Then it''ll jump out of the while(TRUE) loop, call Game_Shutdown(), and kill the window. That''s the only thing that looks different from my code. Peace Out.
