cool & creative idea! Unlike the comments below, I think the text size is fine, as long as you are highlighting the card you want to read. Then again, I played on full screen, so maybe that's why.
Seems whoever goes first is basically set up to win...maybe you can have more spell cards that would help that? Also, the game crashed on me twice when I tried to attack while having two knight on the field. Just thought you should know in case it's a bug! Overall, good job!
I'd appreciate it if you could play/rate my game as well! :)
