The art style is pretty cool, there are some errors at the animation but considering the limited time... For what I've played I find the depth in the movement unnecesary, I mean, it is still not being used for much other than exits on the foreground or background.
Writing is pretty ok/good. Dunno if the story is implemented (haven't seen it start, just walked around and read some of the protagonist's comments about everything -because every building has a line-), but the setting is great, there is quite some detail and care put into it.
