Nice job getting this out on time, the level of polish is impressive! I'm not an expert on card games but I was able to pick this up and enjoy it - I especially like the magic effects animations when you play a card, there is a cool one with lightning that looks great, I enjoyed the choice of music too, unusual for a fantasy game but I liked it. I think you've got the start of something special here, if you could find a way to replace a few of the bigger AI assets with hand-drawn I could see it being a commercial release, you've done a great job! Best of luck with your gamedev :)
