Overall I think it's a very fun and unique idea on a roguelike and auto battler! I think figuring out how the game works and maintaing my little knight was a little overwhelming at first (even after reading the tutorial,) and like many others would appreciate some more visual feedback on moving around the cards. It was a little frustrating that I couldn't neccesarily dictate the timing of my cards so (for example) if an enemy was about to approach and I had a block up, I'd still have to wait for the cooldown and end up getting hit regardless. I'm excited to see if you choose to expand on this game, would love to come back to a more polished version!
Oh and aesthetically very nice :D Very well done!
