Thanks for playing! Yeah, we noticed near the end that the crafting wasn't clear enough and would require some more balancing and UI work to feel less complicated - like unlocking recipes only after gathering an item and clearly displaying what you can craft. Or maybe even limiting the number of stations at the start.
About selling - there is a bug that makes the inventory window inside the shop disappear after first interact with the shop. Which I didn't caught before the end of the jam :/
