So I just wanted to add a reponse, in a location, to a player's attempt to go up.
I've been careless and wrote "You'd need wings to go in this direction."
Do you see the trap for the implementor? If you know our standards for parser-based interation, you will.
Yeah, now the player might want to interact with these absent wings. So I added an object that always says "This is not a fairy tale.". Oops, I did it again. Some players will go look for fairies now.
