I liked how snappy the game feels, such as when cards are dealt. The UI could use some work, though. It's quite hard to tell how much health the player/npcs have and who wins each round, which are both very important to the enjoyment of this game I think.
Here's a vod of me playing your game. Thanks for sharing!
