Could it have been "Ace clear!"?
That means you used the entire deck -- no skipped cards. Nice.
The visuals are fine for me, and I really appreciate the variety of customization options you've included. One suggestion: it would be great if the card design options could also affect the front of the cards, not just the back.
However, I did notice an annoying flaw—when you have a combo at the top, the stack runes are obscured by the score button. This became especially frustrating in late-game situations where I needed to see the stack runes to make strategic decisions.
For example, if there are only seven cards left in the deck and I have a pair on top, I can’t tell whether I should discard a bottom card to complete a triple. Having a clearer view of the stack runes in these moments would make the gameplay feel much smoother.
Nonetheless, great experience!
