You've never made a card game before and you did it quite well. It's not an easy thing to do right, looking at the ones you mentioned or (worse) the old Baten Kaitos.
The music and the sound effects are well chosen. And I like pixel-art, so this is perfectly fine for me.
I found it difficult to understand the amount of fear/charm, until I realized that the layout is different in full screen. The cards overlap the front row, hiding their health bar (see screenshot). And I was never really sure where I should drop the card, I had to redo it multiple times (maybe because of the full-screen issue).
Good job !
