The visuals are great! I love all the little details, like the way the cards move when dragging them around, and the slight movements the cards have when idle. The background is pleasant too. And of course, the usual solitaire win animation is there, and looks great. Getting to that animation took me a lot more than the 9 moves you have in your screenshot though :)
SFX and music are great!
The gameplay is solitaire. Not too much to say there. Controls feel great and are responsive. Only issue I ran into is sometimes the 2nd card in a stack would be rendered over the first card. This would also make me unable to click on the first card, but moving cards around would fix things.
