I like this game. It have potential, but it seems like it's alpha. At the beggining there's not much to do. It totally RNG, because if you're unlucky you will get weak card. And you don't get exp if it's in another tab. So I know what people are upset about. Offline progress don't work for me. Mining is nice. I don't know if there's more content. I'm 65 lvl. Almost reached citrine. I like the progress at this moment. But it seems games missing lot of QOL improvements.
