Visuals are outstanding! I felt it was a little unclear of what to do or how much value there was in destroying certain things. It would have been nice to have a meter that shows how long the current tornado is lasting. Also, I think there should have been extra indication of what the powerups/devil deals did on each card, and maybe a ui during gameplay of the things you've upgraded so far. Overall its greatest strength is appearance and it has a ton of potential. Great job!
