Well...
It is clear that a lot of effort was put into this but there were aspects that just seemed to clash with the overall style and break the pattern of the overall flash. The basic idea here (from what I can tell) is that the whole city is in pixel form, however there were certain parts where it just seemed more like the flash was drawn and just left at a low resolution, instead of each pixel being placed where it should be.
Basically, it seems like parts of this were rushed.
HOWEVER!: There were some aspects that actually managed to convey a sort of meaning despite their brevity. For example the one where the guy is walking and seems to be depressed. When all of a sudden it turns to night, everyone else becomes depressed and he kills himself. This really seems to get at an interesting point of how depression effects more people than the initial victim. So to whomever made that, job well done! Having said that, this was one of the flashes where it felt like they were looking for a style. Meaning it looked like a hybrid of regular animation techniques and the pixel theme, it didn't really work for me.
It's an above average film, but not by that much.
