Very cool experience. Made me really uncomfortable at first for some reason, so if that's the intention, well done! ;)
I really dig the way it opens up and shows you a bigger and bigger weird world as you progress. Gives a really good feeling of more understanding and control over the situation even though it's so abstract.
I did have some issues reading the text, it was often very hard to find the right angle for the blur to sharpen without the text clipping through something. Not sure if the effect is dependant on screen resolution or aspect ratio, when I compare with the screenshots here my play-through seemed much more blurry
