I added a score display and a weighted scoring system; currently, only matched pieces give points (not taking). Points are weighted by the type (pawns are worth more as they are hard to maneuver, queens less), match count (five is worth much more than three), and a bonus for diagonal matches. I also finally figured out how to position the board at the bottom of the screen :P - Doing math in both world- and -zoomed-space had me turned around for a bit.
