First good work. I love the art style and the ambiance. It was difficult, i like this game, but i didn't play with the game, i will explain, i didn't realy play with the card game finaly, because i didn't realy understand the goal, so i just click and i always win. In my first run, i have found directely the princess, but after i have discover the other room.
It's a sad fact that the card gameplay part is the least accomplished. I know my comment may seem a little violent. But it's the opposite, if the card game was more fun and more accomplished in terms of graphics, I'd consider it as my first big crush of this jam (it is anyway). I am critical, because I feel that there is a great potential with your team, congratulations to the programmer.
