Thanks a lot for the feedback! Since this was my Master's Thesis project, I had a tight deadline and had to prioritize the technical architecture over content balance and polish. You are totally right about the blind rewards and settings, in fact the cards information are one of the TODO's things I couldn't complete on time haha!.
Regarding animations: I used both. The characters use Unity's Animator for the sprites (like you see in the game title scene, another improvement could be giving that idle animation in combats too); but I used DOTween for the procedural movements (like attacks, impact shakes, and card hovering) to give it that extra 'juice'.
Glad you see the potential in it!
