Pretty interesting. I never played a deck building game before. While being very confused in the beginning, I think I figured it out for the most part. Eventually I died somewhere on the 2nd "level" because the opponent took control of my knight with boosted stats. Rude!
All the battles were really easy and I barely lost any HP until the last one just obliterated me. Guess RNG plays a big role here. I'll play it again later, maybe I can get further.
Ultra Widescreen support seems to be bugged. Had to switch to windows mode.
Also, in the main menu I have "Upgrades available!" but I can't press the button.
