Hello why this code cant go through last step in validation (Last is: All tiles must be painted the same color)? Game.java:
package com.codegym.games.game2048;
import com.codegym.engine.cell.*;

public class Game {

    public void initialize() {

    }

    public void setScreenSize(int width, int height){

    }

    public void setCellColor(int x, int y, Color color) {

    }

    public static void main(String[] args) {


    }
}
Game2048.java:
package com.codegym.games.game2048;
import com.codegym.engine.cell.*;


public class Game2048 extends Game {

    public static final int SIDE = 4;
    private int[][] gameField = new int[SIDE][SIDE];

    @Override
    public void initialize(){
        setScreenSize(SIDE, SIDE);
        createGame();
        drawScene();
    }

    public void createGame(){

    }

    private void drawScene(){
        for(int x = 0; x < SIDE; x++){
            for(int y = 0; y < SIDE; y++){
                setCellColor(x, y, Color.BLUE);
            }
        }
    }
}
