The card system was really confusing for me and I ended up not doing more than the first level, but the graphics were awesome and I loved the commentary! Card games aren't really my thing so I withhold most judgement, but one thing that really stuck out to me was that it was very hard to read the card values with them being almost white on white. Maybe making the letters gold or something to stand out would help.
Really great work overall and very polished feeling!
