What a gem! The simplicity of the game and unique art style drew me in and I kept playing for discovering more rules. It feels very well thought out and plays smoothly. The little animations and visual effects are so well placed that they're not getting in the way but support the gameplay and atmosphere in a very subtle way. So far, among the submissions I enjoyed playing the most for sure.
One question: The card stack in the bottom left was moving when I hovered it, but I couldn't figure out what to do with it. Am I missing something?
