Big fan of the ambiance! The old-tale vibe is very nice, and the music and visuals match so well!
It is true that the manipulation of cards is a bit tricky (I also did a deckbuilder, and at some point in LV2 your cards move away faster than your mouse, so I know the hustle ^^')
But I really like the fighting animation; it made me think of Inscryption ^^
Congrats on your game!
