The current update seems to have made the game harder. The machinist girl now give a lot less Metal for Coffee Beans than before. At least now I have figured out how to use consumables (food, etc) when I'm outside. It's baffling how the developer can "forget" to tell you something like this. Anyway, I've set up a wiki here. It's pretty basic, I haven't got very far into the game yet (only day ~55). Feel free to stop by and share your strategies!
