Nice game! I like the art style, its very cute! I haven't played many games like this but this one is my favourite so far! Only problem I have is sometimes, when I try using an attack card, I can't actually use it. Even if it's the start of my turn. I don't know if it explained that in the tutorial and I'm being stupid or not but sometimes I can attack and then randomly I can't. And I'm pretty sure I have enough energy/mana to use them. 9/10!
