I love the feedback! Thanks!
Regarding the art, wooh, let's just say that I found out the hard way why Solitaire generally has vertical instead of horizontal cards. Only later, after I finished all the assets for the cards I have realized that they definitely don't fit in there. After redoing everything twice, I've had enough and I just went with the pixelated scaled down version of my original assets. You can actually see how the original assets looked like on the itch page and in the yet to come trailer for the game.
