So I was too euphoric, too bad... but as you say, Smithers, it was worth a try. Thank you for trying Smithers and James!
Anyway, I will provide a savegame just after the rotating platforms, but I assume there are more problems waiting after that. I remember something about the elevator not being in place and invisible Turner not appearing. Maybe, with your feedback, we will get a small series of savegames which will help to overcome that quirky level 15.
Smithers, regarding Lord of the Rings, I guess I'll give it a try although my time is very limited currently... in fact I'm glad that Emperor's Tomb is not out yet - if it was I would never be able to finish my current projects in time
Being in the office currently, I'll come back when I have the savegames available.
