Hollow Knight - convince me to keep playing

Not having anything to spend money on anymore is making me very nervous. I already bought everything that the mapmaker’s wife was selling, so as I’m exploring the greenspace with no map, I’ve got nothing to spend all this money on that I’m accumulating! I could lose it all. Of course that’s nothing compared to how much money I lost in my first playthrough when I didn’t know anything about the game. So I’ll probably still land ahead.
