Needs more UX (highlights, outlines, drop shadows) to indicate when cards are selected and when moves are not available. I ended up with 4 stacks and a Jack - and couldn't complete the game because I couldn't place a 10 of spades onto the jack of hearts (also got the sound effect for a completed stack, without having this jack in it). The myth/legend/folklore angle was a bit weak too, but maybe you could explain it better in game? Congrats on the submission!
