Thank you so much — I’m really glad the opening gag, Reaper, visual consistency, card art, and characters landed for you! 🙂
You also found a real issue with Charity. Its text says it adds 4 souls to the common pile, but the card was incorrectly sharing the Devour prompt from another effect, with no way to cancel it. That is definitely not intended, and I’m fixing it so Charity does exactly what it says.
And no, I didn’t use UI Toolkit for this version — the interface is built with Unity’s immediate-mode GUI, plus custom drawing and animation. I’m happy that the simple look still feels consistent across the game and menus; that was a big goal for the project.
Thanks again for playing and for such a thoughtful report!
