I've been working on a game with levels. I know how to use scenes and transferring to scenes for the levels but it's getting laggy and slow. I know I can just do 'Start Game From File'. That will start the other blend file. It works, but the problem is when I save the final game as an exe or Game Engine Runtime it doesn't work. When ever I select the option to go to the other blend file it just quits the game.
