Nice visual effects, especially the glowing!
The game loop took some time to understand. The hardest part to learn was that cards that scroll at the bottom apply their effects automatically by some cooldown, and the cards you pick are not applied immediately ("hey, I picked multishot multiple times, why nothing changed? ... oh, that's why....")
It would be cool to have some hint of the applied card effect, as it is challenging to keep track of them in the middle of the fight.
I also thought that "restart" starts the game over from zero state, but apparently it only resets the card effects, and the deck stays with you forever.
Once I got used to these rules, it was very fun to hunt for calamari ¦3
