Very enjoyable and addictive game loop. I work in Godot and did the UI in last year's game jam, so I was really pleasantly surprised by how effective the UI is here. I'll take a guess that you may have used Godot 4.7 for the card-in-hand effects...
My only criticism really is that the paw on mouse cards weren't quite different enough to distinguish from the paw by mouse cards on first glance, so I thought these were playable together - a minor blip of frustration when I found out they weren't.
Other than that, a solid submission and congratulations on entering!
