Wow, this is a very cool and polished game. I really like your art style! This game looks amazing and also feels amazing. How these balances move feels so satisfying and the tutorial is also very good! Maybe the gameplay could need a bit more variety, as after a while you just play almost all the cards without thinking about it. Of course the balance mechanic added some thinking, but maybe it needs another mechanic. One small detail which I would also change is the indication what the influence of a certain card on the balance is. At the moment the colors indication which balance it affects and the text indicates which side. I would change that around. The text (and the position on the card) tells you which balance it affects and then you have a color for the left or right side. I think this way you get a faster overview of your hand and can plan the strategy.
Congratulations to a very cool entry, especially the looks are perfect!
