Checkers game

Hi,

I’m developing a checkers game for an online game site. Please take a look and give me a comment.

Ps: This checkers is still in developing, so there is no score, time or player won alert.

Ps2: The game uses the brazilian oficial rules. In this rules, man can capture in every direction and the king may move a lot of squares. Also, the player must play the option that captures the biggest number of pieces.

Ps3: Some portuguese hints:

Cancela = Cancel
Damas = Checkers
Branco = White (pieces)
Preto = Black (pieces)
