Thank you for your feedback!
What I'm gathering is that my priority after the rating period ends should be to update the game with an instructions screen with visual elements ("anatomy of an order" etc.) so that it's easier to understand how to play than the text-only description can enable. This was something I was planning to include! but couldn't justify when I was over time as it was.
I just finished making (and will soon publish) a related game, Tea Run, which uses the (dice-selection) lavender color for each table/order's teacups. That's a tweak I can also make to Tea Time that should prevent that particular (understandable!) misunderstanding.
