I like the mood. I'm not much into card/dice games, so I can't say much about it. Obviously a tutorial is needed, but I guess that's clear, and right now it's just a prototype...
It feels weird that a player has to pass when he can't play anymore. So maybe automatic pass would be better.
(I've spotted a small bug: After going to full screen mode, the cards are not enlarged anymore when hovering on them.)
