Super Chess!

May I introduce you my chess game. I'm pretty sure I forgot to implement some game rules: just movement and capture feature are implemented. I didn't have time to animate it (it was out of the scope of my project). To play: 1) click a piece you want to move. A special indicator appear around the piece; 2) all cell you can move to are put in evidence by a red spot; 3) all pieces you can capture are surrounded by a red ring; 4) click the cell you want to move your piece o the piece you want to capture; 5) use key "A" and "D" to rotate the game board to have a better view of the game;
