Not much of an item suggestion, but I'd love to have more dialogue with the dealer during the game. Her cocky laughs when she's winning/you're loosing a really sells the game. Having her react to gameplay events with some quips would make the match personal. When things are more personal its just that much more fun to win... or loose.
Sorry if this suggestion is too late, just found this game recently, but either way thank you for your work! Excited for the full release!
