   I made it easier for me. Changed the size and colors. Just change psiz=.. on 2nd line. Here is the barely modified code:

   int[][] field; int psiz=2; int psiz2=psiz*psiz; int state = 0; PFont font;

   void setup() { size(300,300); field = new int[psiz][psiz]; shuffle(); font = loadFont("LucidaBright-48.vlw"); }

   void draw() { background(0); if (state == 0) {

   for( int i = 0; i < psiz; i++ ) { 
     for( int j=0; j < psiz; j++) { 
       if (field[i][j] >= 0) { 
         fill( field[i][j]*256/psiz2, 196 - field[i][j]*128/psiz2, 72+field[i][j]*160/psiz2 ); 
         rect( width/psiz * i, height/psiz * j, width/psiz, height/psiz);
       }
     }
   }
   

   } else {

   fill(0,255,0); 
   textFont( font, 48 ); 
   text("You Won!", 70,150); 
   textFont( font, 16 ); 
   text("(Press any key to restart the game)", 50, 190);
   

   } }//draw()

   void mousePressed() { if ( state == 0 ) {

   int i = round( mouseX / (width/psiz)); 
   int j = round( mouseY / (height/psiz)); 
   move(i,j); 
   if (check()) { 
     state = 1;
   }
   

   } }//mousePressed()

   void keyPressed() { if (state == 1 ) {

   shuffle(); 
   state = 0;
   

   } }//keyPressed()

   void move(int i, int j ) { if ( field[i][j] != -1 ) {

   for( int a = 0; a < psiz; a++ ) { 
     if ( field[a][j] == -1 ) { 
       if ( a < i ) { 
         for ( int t = a; t < i; t++) { 
           field[t][j] = field[t+1][j];
         }
       } 
       else { 
         for ( int t = a; t > i; t--) { 
           field[t][j] = field[t-1][j];
         }
       } 
       field[i][j] = -1; 
       return;
     }
   } 
   for( int a = 0; a < psiz; a++ ) { 
     if ( field[i][a] == -1 ) { 
       if ( a < j ) { 
         for ( int t = a; t < j; t++) { 
           field[i][t] = field[i][t+1];
         }
       } 
       else { 
         for ( int t = a; t > j; t--) { 
           field[i][t] = field[i][t-1];
         }
       }

       return;
     }
   }
   

   } }//move()

   boolean check() { int c =0; for( int j = 0; j < psiz; j++ ) {

     if (c == 15) c = -1;
   }
   

   } return true; }//check()

   void shuffle() { int c = 0; for( int j = 0; j < psiz; j++ ) {

     field[i][j] = c; 
     c++;
   }
   

   } field[psiz-1][psiz-1] = -1; int x = psiz-1; int y = psiz-1; for(int i =0; i < 16; i++) {

   x = int(random(psiz)); 
   move( x, y );
