Hmmm, I couldn't figure this one out, unfortunately - possibly because of issues with my potato of a PC and running it in wine on Linux. At first, I thought I had to avoid walking into lighted areas, but it did not seem to make any difference - any time I moved forward, I ended up being reset at what felt the exact same point.
it running really choppily, unfortunately, meant I also did not have a lot of energy and motivation to try it for a long time and experimenting what else might be the objective.
