Hi - I'm having the same problem, and I'm sure that this is some sort of bug.
At first everything was fine; I could navigate around the maze as one would expect (I've been through it before, about 10 years back).
After spending quite a while navigating in each direction, I managed to get myself into a point of no return. Simply put: the direction I arrived in is no longer available to me (the viewing window shows a red dot, and won't let me go back). My game is at a point right now where I only have 2 "stations" that I can visit, and can only traverse between them on a single path.
It's almost as if the game has lost track of the "state" that I'm in, and I'm trapped.
In case it helps diagnose the problem - the maze was fine at first; it was only after navigating through it for a long time that I got cornered somehow.
