Thanks for the feedback. Yes, unfortunately the game keeps on playing even when someone has no cards anymore, but I ran out of time. Did you mean this by breaking?
I would have loved to add so many things. My plan was to have an easy starting game and than ramp up the difficulty, maybe allowing you to customize how difficult you want to play (number of starting cards, see other player cards, etc.). It's actually all there, but like I said no time for UI.
