I'm running the game on Chrome on Windows, with keyboard input.

Whenever you enter a new area, a couple of straight white lines will appear for less than a second, usually only if you're right after you enter, connecting Val's head with some other point on the map. It's doesn't matter which area you enter, and it's always the same point on the map. For example, when you enter the Deep Town, a couple of white lines will appear, connecting Val with Tara (I think).

I don't have a screenshot because they appear for a very short amount of time.
