Just got both endings. So, yeah, to continue a little what was being said in
http://nifflas.lpchip.nl/index.php?topic=3874.msg45691#msg45691, this has the right pieces in it to make it feel like there is a story even though there is not. Lots of pieces feel like they fit together, though, even if there is no reason given for them to do so. I guess I should put this in spoilers because I allude to ending areas...
You have the machines, the trick end that almost feels like a set up by an adversary, those cool floating gear works, the dark, the white, the ancient section crowned by an endless wall, and waking up to find yourself in a green living area instead of a red wasteland. Those are good pieces and they can be read in various ways. I like it. :) The only thing I see that could confuse a deeper ending would be that the white area isn't really all that different than any others. Normally, I would assume that a white area would be an opposite of the Darkness. Instead, it is the ancient area which holds the most significance, acting as the endless path to yet another Darkness, but one lacking the foreboding music (though visually it is still foreboding) and which leads, apparently, back to normal life. That creates a strange image if one is trying to create a deeper meaning.
