Great atmosphere, great art, only a few technical / narrative quibbles. In the end, my greatest impression was that of standing awkwardly in the kitchen during a college party while a horrid breakup happens just one room over, shoulders way too tense as you sweat into your t-shirt and pretend you're not also anxious about everything.
More specifically for the art, the sudden cuts -- with music and sprite changes -- were really well-executed, and created some genuinely frightening and fascinating scenes (like, they're really, really well-done). At the same time, I found that my eyes were most often at the lower-right corner of the screen, and it could be difficult at times to properly look at small changes in character expression or the like.
The writing also felt -- in some moments -- over-expository, but other scenes really do stand out in terms of well-written character action (the music festival in particular had really good dialogue and action pacing!), and the overall atmosphere is great. The story itself wasn't exactly my thing, but it might just be yours, dear reader, so give it a shot... and either way, the combination of nighttime city lights, ambient music, and listless wandering is well worth anyone's time.
