I enjoyed the topics about gender and I think they were presented in a mature way. I liked that the main god was a man and his 'counterpart' was a woman and 'everything else'. Also, the end was a bit bittersweet but a bit encouraging too.
The story of the god was really fun, I liked that he destroyed the cross with martial arts to create the new symbol. The story of the gods was interesting too: there were lots of gods and at the end only one prevailed while the rest was in the shadows.
My only issue was that I was expecting to play cards with the sexy demon lol! But obviously it wasn't the goal of the game. And the art and effects of the cards were really nice.
