ah, thank you! The full game intends to have Buront go and find items and talk to other residents of Gensokyo, and he'll be able to help them with errands in exchange for more items, and he'll be able to craft some things too, and both help make the summer festival as much of a banger as possible and also get more stuff to talk to Rinnosuke about. The item infodump system is going to be more choice-based conversation style than the format of the discussion for items within Kourindo, and I'm considering giving it a sort of points-based system where your responses add to a point total that determines an ending
I'm glad you enjoyed the references too! I worried some of them may be too obscure, but Kourindo is a shop of obscurities so it fits right in
