Simple, nice, and fun game! I really liked the 3D view of the cards as well. I’m pretty sure you already have so many things in mind for the next stages of development, but I wanted to give you a few suggestions that might have a positive impact on your brainstorming.
Opening card packs could be awesome, or maybe some kind of gacha system where you actually collect cards. That could add a nice sense of mystery and excitement
You mentioned that you’re not a coder, but it might even be possible to add a small, simple AI-powered game where you can earn some gold, complete little activities, and use the rewards to get new cards, etc.
I believe this is the first browser game I’ve ever written a comment about! I also uploaded a gameplay video, and I hope the Kodkod community enjoys it as well!
