In my other guise as a writer for the website Comics Bulletin, I wrote a review of the new Studio Ghibli film Arrietty. I mention it here because the opening twenty minutes or so consist of an exploration of the nooks and crannies of a family home, but the diminutive size of the explorers gives the sequence a sense of epic scale.
It occurred to me that if one were to put aside the fact that a ladder was made out of nails and so on, that these sequences were great inspiration for adding little bits of flavour to a dungeon crawl. Why have the characters walk down a corridor when you can instead have them slide across a narrow ledge, or have to hop across a gap here and there? I don't think it's even necessary to attach dice rolls to these moments -- unless of course there's a gang of hobgoblins chasing them -- but they'll add a bit of flavour to the explorations.
