I got stuck in the first turn of the second battle not being able to play my cards or end the turn.
I wish the buttons had some change when you hovered over them for me to tell if i was going to hit them or not.
I like the pixel art, and the old-school nature of it. The card UI almost felt too smooth compared to the rest.
Launching into the battle without any instructions or tutorials was a little tough, so I had to go looking for the text document.
Biggest thing for me is that the window was not re-sizable, and I am running on 1920x1080 monitor, which seems like the right size, except, I couldn't maximize it either, and the window bar made the bottom of the game get cut-off. so maybe I got stuck due to that? I couldn't really read the card text easily, but the tool tips helped a lot.
