Thanks for playing! Hailing ships is the key to acquiring or resolving quests. Perhaps I should just add a "sell" button to the gardening screen?
A sell-button is not a bad idea! Or if you prefer to do the "selling" somewhere else, maybe the Garden could show some sort of hint, the first time you harvest a plant, telling you where to go and sell it?
That's a great suggestion. Some more prompting to guide through the game loop the first time through. Thanks!
