It was confusing at first. I had no clue what to do, I wish the game mechanics were explained in the game or in the game description.
But once you start to understand, it is great, great atmosphere, great art style, music fits the game perfectly. Nice finishing touches here and there, it feels polished. Game mechanics are cool too, simple yet enjoyable and quite profound.
Nice work on the balance too, the game isn't too hard nor too easy! Well done in that regard!
I just want more!
Edit: the enchantments that refer to other cards are very confusing at first, something like displaying the name in another color or event displaying the referenced card when you hover its name would have helped me a lot :D
