I've been making a few maps recently, and I'm stumbling across an issue that's kind of bugging me. You make your map, it looks okay, but there's all those edges with nothing stopping the player from derping into the border, like the map below. As a general rule of thumb, do you think this okay if the player isn't transported to a different map upon touching the edge? Or should an attempt be made to block off those areas? If so, what's a good way to do that without relying on cliffs/forests for every. single. map?
