Nice work so far, the game's UI and art is great. I was initially confused on how to play because I went straight into a fight and I had no cards, I'd probably give the player a default deck or force them to make one before entering a fight to avoid confusion. I'll also add the first fight was pretty tough. Those issues aside I'm interested to see how the game develops, I think it has a lot of potential!
Thanks for the feedback! I believe the no card part is a bug. We will fix it in later patches. It would be kind of you to give our team a in depth feedback here: https://forms.gle/z3onjhDnXcdeeutw5
