Really great work, the artwork and polish are fantastic, everything feels and looks really good. I especially like the little face animations for the devil, wonderful detail. And the animations of his finger moving the cards around!
The cardgame is quite fun once I got into it too, though the tutorial felt quite long. I think I don't really see stealing as being that big a part of it, so the take on the theme remained a little obscure to me. And ultimately whilst the cards are negatives, it plays like most cardgames on pairing high cards together, so I don't know that it feels like a distinct mechanic.
But in any case it's a lovely entry, very well done!
