(i had commented earlier, but maybe forgot to push "submit"?)
really nice idea, and well-fits the theme, nice art direction, smooth animations, intuitive "snap" when releasing cards - so, good "ui" mechanics throughout. sadly with that much effort on the deal/shuffle/play interaction, i get that 4hrs isn't enough to actually put something "playable" together. still, call it time well spent if used as a 'keeper' framework for other card games to come. (ie, this seems a "practical" effort) so if I -1 for not-playable it maybe washes out with a +1 for solid useful 'foundation' code.
