I have to say, the parser isn’t the greatest here, usually there are different messages for doing commands wrong than an endless stream of “Sorry, I don’t understand that command.”

It looks like instead of using a real parser you just made certain responses elicit responses depending on what room you’re in, is this correct?

I think this because there aren’t any use <item> on <object> commands, it’s all just some form of use <item>.

Could you at least make <get> <item> commands say “There is no <item> here, or something?
