Visually stunning, great music. Will say that whistle sound effect does get annoying after a while haha. Didn't have time to play through much of the story but it's a funny idea. Great job!
A little more feedback during gameplay might be nice- I agree with what others said, it was confusing at first why I was winning, even knowing the cards left was the enemy counter (i think a few times i won when it said 9, or sometimes the enemy drew multiple cards? it was confusing), and also when the enemy played a card it was a bit sudden. Also, I know it might mess with the aesthetic and make it more like UNO, but having different colors for the different letters really might help, I had a little trouble just deciding what cards could be played or not. Maybe just me though.
All that being said, what a cool game, can't believe it got done for a jam!
