I actually rather liked the level. It creates a very unique, dream-like atmosphere, especially with that wonderful crackling piano recording. Though, as WreckSauce stated, you cannot see the path to take, I found it was easily discerned by the tried-and-true technique of holding left and up while pressing S occasionally.
The few screens where the city fades out and you enter a barren expanse of sepia in which misshapen structures begin to loom in the background was my favorite part. I thought the white background of the phonograph was a bit jarring, and though I enjoyed falling after its music was silenced, the final screen seemed perhaps too abstract and anticlimactic, even for a level so abstract and anticlimactic itself. However, you said this is merely one part of a larger level, and I assume this issue will be resolved in the final product.
