I'm not too sure if it counts as a form of exploration storytelling but I would say that is the closest form. The game is very simple and mostly consists of the tea shop worker telling you about the various types of tea they sell. As someone who knows nothing about tea other than that Green Tea and Earl Grey exist, it was nice to learn a bit about a bunch of types of tea. I liked the tone you went for, being a more laid back and comedic one.
Overall, I liked it and its tone, looks, and color palette. Guess if I were to recommend anything, it be to be give the ability to buy one of the teas I guess.
