Hello!
After several days playing this game, i've got stuck in a dead end

SPOILER


In the observatory at Hambletone's house, I saved the game after glass sphere that falls of the roof breaks on the floor, and now I can't go on.


END OF SPOILER


I would like to ask if someone has a saved game around that moment. I searched but I think that doesn't work in the GOG version. I'll be very grateful, because beginning the game again at this point seems more like a torture for me.


Thanks!!
