Hey, I liked your game. BUt I think it's a bit short. I'm also doing a card game and trying to come up with the design ideas for it, but don't have a playable demo.
But I've developed a web-tool for generating cards. Maybe this tool will also help with development of your game.
I would be gratefull if you can take a look and provide any kind of feedback.
