White City [Environmental]

The difficulty for me with that one was essentially due to the fact that I climbed the "inverted well" before getting the eye powerup, so I was sure all of them were dead ends. Indeed, to actually notice the new passageway one actually needs to follow the correct path, not simply get to the screen, because it is pretty much invisible and the detector only fires when we are very close... I am not sure how I would fix that, though. Changing the architecture would of course be too much, but perhaps extending the detector signal a bit farther away, so that one can see it even when going up the big path?

I just played through myself. It strikes me odd that you need to have the eye power to access the key, but the hidden passage is not marked by ghost passage indicators. All the other ghost passages are marked.

@egomassive, I think there are ghost markers, I see them in the level editor but not when I play the level. I think the water falling up is disguising it so that you can't see it or something.

I think it would help the level a bit if you made it more obvious, but it wouldn't help it a lot. I really don't think it's worth the effort as the level is fantastic as it is.

My interpretation is as follows: The White City was a digital realm, a supposedly perfect "matrix" so to speak. I believe this because the architecture seems to elicit thoughts of circuits and silicon, and its the easiest way to achieve true perfection and equality. Not only did the people soon grow to dislike it (people enjoy feeling superior, they enjoy getting back up after they fall) but something... else happened. Perhaps their physical bodies started dying off and people started vanishing from the city? Eventually everyone realized that a perfect illusion isn't perfect at all and woke up to the physical realm to live real life again.

Don't think there's any need to make the purple key more obvious, I found it right away with the light powerup, before I even had the eye to retrieve it.

I must admit I have bigger problems with finding blue key than with purple key, because purple one is visible from another place.

@egomassive, I think there are ghost markers, I see them in the level editor but not when I play the level. I think the water falling up is disguising it so that you can't see it or something.

It is because there are two almost identical screens (because of crossing corridors). In the game you can only enter the one without markers.

It seems to make the most sense to expand the sensor area out into the main chute so that the player can at least sense it as they fly up the tunnel.  That way, if they at least have the sensor they can get clued in.  And I'll fix the ghost marks.  I think I built it this way because I was trying to use all the power ups.  That will give two clues.  I don't think I'll add more than that.

I don't actually have a set in stone answer to what is going on.  As you said, there is not absolute truth, not even in the specific instance of what is happening.  But you are very close.  I envision the White City (as well as Vague Feeling) as not so much being in a virtual reality, but in a reality that has been programed somehow.  I love the idea that they begin to die off and leave by waking up though.

...that it's...well, just some sort of "higher plane". Could be a digital wonderland, or an actual heaven of sorts. Point is, it's a thing and it's perfection. Everyone is more beautiful there, everyone is more healthy there, everyone is just perfect. But they start to think, what's the point of life if you have nothing to work towards? Sort of a "happiness is not a destination, but a path" sort of mentality, which I agree with wholeheartedly.

very close!  I'm unsure how perfect the people were, only that they thought they had made the perfect place.  The question is, how do you confirm that a place is perfect, and indeed, what is the point of life in an unchanging perfection.  So they moved on to continue life as an act of discovery and relationship.
