What does the spinning cross and the blinking circle on the map mean?
I guess one is your goal, what is the other one?
Answer
The spinning cross shows the room where you last entered the map. The blinking circle shows the room where you were last located when you pressed Esc. The grey lines and squares show the path you took since you last entered the map.
For completeness, a large square indicates a room where you have not found all the exits, a small square indicates a room where you have found all the exits, an arrow indicates an exit (apparently only in one direction) to another part of the map, and a circle on an exit indicates a dead end.
As an addendum: It appears that the untaken exit symbol can also indicate untaken entrances (remember that in a non-Euclidean game like this, there is a distinction).
