Visually this game is very nice. The characters, cards and UI all look great. The UI is easy to navigate and use however some elements did appear to be slightly off screen. I'm not sure if this was a design decision or technical error.
The game could really do with some sound or music. It is quite dull to play in silence. Sound effects would really add to the nice visuals you already have going on.
This definitely needs some kind of tutorial or way to let the player know what is going on and how to play. The card descriptions are mostly about reducing wildness or gaining courage but I had no idea what this meant in terms of game play. I just randomly selected cards until the game ended.
Nice work :)
