Sorry about that. I just tried to replicate that and nothing I type crashes the game for me. Also "get" isn't a valid command, but I'm not sure why it doesn't give the error message when "get" is typed. It should also show encourage you to try "help" if an invalid command is typed. I would update this, but the working version I have is quite a bit beyond this demo so I'll probably just wait until I can post the full version. Sorry again.
