Managed to get some screenshots in from the Bergmann tunnels.
So far I’m still enjoying it. There are some puzzles which is not so straightforward, and which need a bit of cheating with google to get resolved.
Everything seems well thought out, but sometime you need to do a lot of walking to and fro just to get a puzzle resolved.
Of course you can just play the game from start to finish without doing anything, but what’s the fun in that?
