Incredibly fun core game loop here! It does take a while to understand the game and attack vs keep deck alive mechanics, but once you do, it turns into an interesting gameplay that you have to think quite a bit. It's a challenging game!
I feel like everything you have in your game I could have blended into mine, as it also have cards haha
Really nice job!
In terms of improvements, I think that during the game play it took me a while to understand what each card did, so visual tips on mouse over would be nice. I found it clever that the "attack" is the total of points, it's almost like you mixed blackjack and tarot here!
Congrats on your game!
