This gave me a neat idea. In my game, I made some priests and nuns able to heal specific ailments to party member(s). Well seeing the status shop in your demo, I misinterpreted it as HER providing said status curing services, not items (bit sleepy atm).
Its probably possible to common-event it via a shop menu instead? EX: "Buy" Resurrection = 1 party member (or all) are revived. Would greatly cut on each NPC's event page length. Easy to add or remove purchase-able services... Ill need to make a bunch of tests to see what Im able to pull on my own, but I may get back to you later on the matter (a week+ from now).
Nice. Shopkeepers and you (owl) providing the player with coins. How considerate! >;3c I know... debugging and all.
