I love the aesthetic and idea, very cute and cosy and I absolutely adored the card art!
I think that I'd have liked to see the game lean more towards its puzzle element, since I often found that just going straight and using what I had never made me run out of anything I needed. I feel like there could be some strong eureka moments if the puzzles where smaller and more intentionally designed. Apart from that, having more info might be nice, being able to hover over an enemy and only see their attack pattern (maybe something to indicate there movement too).
