Nice idea and cool game overall. Art and music are great.
Apart from the UI issues mentioned in other comments, I found it weird that when using a card to move in every direction, you can input a direction with the same key as moving the camera. Sometimes I didn't know where was my character because of that. The other issue was the randomness of the cards, if you don't have luck you can be forced to hit a wall multiple times before getting cards to progress.
Good job to all the team !
