Nice idea. But I not sure I understood the cards.
Each played received 3 cards. I think you should make an animation where we can see each player receiving 3 cards (here, we see 6 cards going in a hole, there is a distribution animation missing)
Also, I don't think you should put in small other logo on each cards. I wondered what it means. But it's only a reminder isn't it?
With this kind of little change, the concept that go will shine. I already played shifumi. But not like that: it great to bend some game to create new ideas like that. I love it! congrats! 👏
