Once I figured out the rules, this was very fun. My biggest nitpick is that the enemy choices feel random. I'm assuming there's some sort of algorithm, but I think single player card games benefit more when the rules are laid out clearly and the player is in charge of every action. That being said, I did find myself playing the game as if I was going against a real person and not some computer lol, so that probably speaks to how immersive the gameplay actually is.
The sound design was awesome, and I think you did really well making the Inscription inspiration pay homage without directly copying it.
Good work!
