Thank you, Teper.
Re: what Aptequar said about the places being ephemeral - I meant to reply to that, but forgot, so here goes:
Well, from a philosophical standpoint, *everything* is ephemeral, of course ;-) but there are degrees to this, in the level (as in reality ;-)). Also, there are different senses to the word ephemeral, I think... one being something close to 'transitory', and the other, maybe, closer to, though not identical with, 'ghostly'?
The city is, well, like the intro screen says, essentially something like a ghost, or a memory. There used to be a real city there a long time ago, and maybe some of the boulders and rocks (especially the more rectangular-looking ones) aren't boulders and rocks but the remains of its ruins... but the lights that appear only at night are not a physical phenomenon. (So maybe *they*, actually, are not so ephemeral at all - in the sense that they will always be there at night, because what isn't physical doesn't decay...?)
The
I think, is real, and not particularly ephemeral (although it is, of course, a symbol of the transitoriness of every form of life).
The
may or may not be ephemeral. I don't know any more about it than Juni does.
The
in my mind, is not ephemeral, although it probably only looks spectacular in the dark. In my mind - but you're free to your own interpretation, of course - it's a little patch of nature developing rich and strange new forms after the fall of the civilisation of the city. A real and tangible sign of the future, if you will.
And Juni's village is entirely real and non-ephemeral, of course - but it is also quite obviously a dying place, visibly built from the scrap of that long-dead civilisation.
(The crazy old man's bouncer village probably derives from a futile, in fact insane, desire to stay that decline.)
