Thanks for all the great ideas Laura! ( And for finding that bug D: ) I'm glad you're enjoying using the project; I'm having fun making it! The usability ideas and feature ideas are all solid, so I'll add them to my backlog.
Probably the trickiest thing to add would be the map one; I'm guessing you're imagining a larger grid of rooms? It does sound useful though.
Another question: what character limit are you thinking of for the dialog? The number of characters per "page"?
