meh
it's a nice idea but it just has too many flaws.
first of all: the pieces can moved everywhere, no matter what movement-limitations that piece has or if there are other pieces in the way, etc.
then, there are no "turns", mea´ning that the white pieces can all be moved one after another without moving one single black piece.
also, the pieces aren't snapping to the grid, which sure would have been a nice feature. instead they just "hang around" somewhere on the board.
furthermore, a little sidebar, showing what moves had been made and when (for example: 1. e4 e5 2. d4 f6, and so on) would have been very nice, too.
as i said: this is a nice idea, but it needs a lot improvement!
