Sorry, piece & move select functions upon mouse release not click. Drag and release is def broken for some pieces.

Change was subtle by choice. Decided to keep the change simple due to time constrains. I am no chess expert but kept with this variation curious to see how removing the ability to safely block your opponents pawns lane would impact decision making in the mid to end game. A weakened back file piece is no longer safe in front of  a pawn. 

Was hoping this would add an extra element of rock, paper, scissors working as an option to attack the safe possible moves of a weakened piece.

Theme score is totally fair, they are not excessively overpowered. Appreciate the feedback.
