in greenfoot the user.class is removed after 1.20 seconds but the website is not removing user.class 
//timer.class
import greenfoot.*; 
import java.util.List; 
public class Timer extends Actor
{
    int time=0;
    public Timer()
    {
        getImage().scale(1,1);

        World world=getWorld();
        Start start=(Start)world;
        List objects = getWorld().getObjects(User.class);
        time++;
        if(time>80)
        {
            getWorld().removeObjects(objects);

Try: 
// world
import greenfoot.*;

public class Start extends World
{
    static GreenfootSound sound;
    
    public Start()
    {
        super(800, 600, 1);
        sound = new GreenfootSound("mini.mp3");
        addObject(new User(), 130, 50);
        addObject(new Enter(), getWidth()-420, getHeight()-127);
        addObject(new Info(), getWidth()-420, getHeight()-565);
    }
    
    public void started()
    {
        sound.playLoop();
    }
    
    public  void stopped()
    {
        sound.stop();
    }
}

// user
import greenfoot.*;

public class User extends Actor
{
    int timer;

    public User()
    {
        String name = "Alien";
        if (UserInfo.isStorageAvailable()) name = UserInfo.getMyInfo().getUserName();
        setImage(new GreenfootImage(name, 37, Color.YELLOW, new Color(0, 0, 0, 0)));
    }
    
    public void act()
    {
        if (++timer == 80) getWorld().removeObject(this);
    }
}
In Enter and Info classes' act methods, add the following line for when clicked on: 
Start.sound.stop();
Delete the Timer class.
