Very well-designed combo puzzle card game. As a card game enthusiast, I really enjoyed playing it! This game is so underrated and deserves more attention! A small improvement I would like to suggest is to mention how the enemy will behave, or what cards are in the enemy's hand. (Like: Does the enemy have a bear?)
I think you should keep developing this game and release it with more animals (as well as levels). I would love to see it in the future!
