great job! you nailed the art style and feel.
I'm not a fan of poker but the gameplay is really good as well.
As much as the story is good, I'd start the description with how to play; it was a little hard for me to understand since I don't know poker. Also, sometimes it wouldn't let me place a card... not sure if it was a rule or if I had to move the mouse exactly to the center of the slot.
I'll be following the development!
