What do you mean by polish?
Because if you asked me i would say polish is one of its biggest strengths. The cards move "smoothly" and glow, a lot of the elements are "animated", there are different transitions, etc.
I'm not saying that you are wrong, the game needs polish, but compared to the other elements i thought that it stood out.
I'd love to know more about your thoughts in this and thank you again for playing and leaving your feedback.
