The second one.
Can you please clearly say every step because it's really unclear :/

To change what danpost wrote, only slightly: In your Countdown_3 class (and any other intermediate world classes), add the following: 
    private World previousWorld;
Then change your constructor so that it looks something like: 
    public Counter_3(World world) 
    {
        super(...); // keep this line from the original constructor!
        previousWorld = world;  
        // add anything here from the original constructor
    }
Then to return to the previous world use: 
    Greenfoot.setWorld(previousWorld);
If you try this and can't get it to work then post the code you've written.

If i do the steps you told me i get "cannot find symbol -variable previousWorld"

Please show the code for the class that the error occurs in.

Comment out your changes, open the debugger and 'Terminate'.

How do i do this?

I presume your 'Run'/'Reset' buttons are not usable and the Compile button appears to be usable, but does not do anything. Your program is probably in an endless loop. Comment out everything in your initial world constructor after the 'super' call (leave the first line un-commented). Then from the menubar, select "Controls>Show Debugger" and click the 'Terminate' button that appears on the new window and then close that window.

Post your world class here for further assistance.

my run button does work, i have a main menu but it doesn't start a new world after the main menu! http://pastebin.com/uDM7VzHP

I think you really get the idea wrong! First when i run it, it start the main menu, if i press space it starts BackgroundLvL1, when BackgroundLvL1 is over i start Countdown_3 --> countdown_2 --> countdown 1 ---> countdown_go ---> And then again BackgroundLvL1! it's an infinite loop!

I think you need to show your main menu class code (since it is what start the new world).

I forgot to mention when i launch the game it first shows an intro but after that it's the whole loop but yeah now the main menu launches the Intro world but i will show both! Main Menu:

So, what is it that is not working properly now? when the spacebar is pressed, does it go to the Intro world? does it run its course and then go to the BackgroundLvL1 world?

#
At the end of intro it doesn't start, the game stops and an error appears, because i changed public background() to public background(World world). My bet is i have to call it with in a different way but we cant use previousWorld because we define it in BackgroundLvL1 itself.
