Extremely low polish; full of typos and grammar issues, art is generic, poor sound design, and touch controls painfully unintuitive. The most important thing, the cards, are depicted so tiny that I can hardly read them without zoom. Landscape only. No left-handed option. The worst is that even though this game is paid, you get constantly beat over the head with micro transactions. I instantly refunded, because I buy games to NOT deal with freemium trash.
