Absolutely loved the Art Style in this game. The cards have their own flair to them that's adorable, and even with the "cuteness" of them it was easy to understand what each card was meant to be. The artist for this game has found their style, and is nailing it.
I really like the premise of the game, and a simple How To explanation on the Title screen would work wonders. Took a while to understand what was happening though. I wasn't sure why I couldn't or could play certain cards, but after a while you figure out things little by little.
Overall, solid entry! Great job!
