I just purchased this and noticed that only the first card player works, apparently because it's using the plugin command... If I talk to any of the other four players, the game crashes with the "Reference Error: tripleTriad not defined" message -- those player events are using the script call instead of the plugin command. I wouldn't have understood this if I hadn't seen another comment here that mentions it, so I guess the demo file still hasn't been updated... And even when it works, I can sometimes get into a situation where the game simply crashes in the middle of a card game, with the message "TypeError - Cannot set property 'undefined' of undefined," but I don't yet understand the rules of the game well enough to guess what went wrong.
