Not bad. Still not too hard to do by hand, as you can follow most side passages to a termination by eye,or follow the blue walls and see that they don't have a break so there is not a path in that direction, but I don't know how you go about making it trickier. There were a good number of side paths that went a reasonable distance. I should have timed myself. I just copied the image into paint and use the pencil tool to trace the path.
