A map or compass could help. Also, when I made a game that had a travel style similar to this one, I gave each room its own unique name and would say "Go left to [room name]" to help myself (and players) keep track of which room was which and where it was. That's a more in-dialogue way to do it, I suppose. I'm sure there's people with waaaaaay more experience under their belts that would be bigger helps than me. xD
