Hi Betje - and MaG
I will dig out my notes and see what I can resurrect. I can't recall the details.
I remember you end up outside, and there are three seperate paths through the fields and hills that lead to the different endings. One takes you back to the room you started from, but thats all I do remember.
I certainly did not discover any deeper meanings in the wine bottles. That doesn't mean there aren't any.
A word of warning re the chimney. Once you get through there is a lift. Press the wrong buttons and it will send you back to the start of the chimney again

But once you are through you will probably be able to manage it again. I certainly found the first time the hardest, and in fact needed Pokey's help.
I will let you know what I dig up.
