I guess now that not only is the changelog public but also the bug tracker, it's not exactly a secret anymore who's been doing what, and I can at least comment on some general stuff now (you should've seen me trying to act all casual replying to the last big blog post, heh).
Is it the most amazing-looking game ever? No, but I don't think anyone ever expected it to be, and if that's what you want, you can go spend $60+ on something with a budget of tens of millions of dollars with dozens or hundreds of artists behind it. Not everything in AVWW quite fits together perfectly, and there are plenty of nits to pick while looking at screenshots or videos, even uncompressed ones to a lesser extent, but what else are you going to do with a screenshot other than stare at it and pore over the details? It's not like it's interactive and you can play with it.
While actually playing the game, on the other hand, there's no time for any of that, and what matters more is whether things serve their purposes of being recognizable and distinguishable. For the most part that's been true while also generally being in the range of looking "good enough" to "actually good" in the context of "what you're able to see while running around as things are trying to kill you and eat you", and there really hasn't been much that stood out enough to distract me from either playing the game normally or attempting to find creative new ways to make the game stop working.
Amusingly enough, the stuff people have been griping about with the artwork and way the game looks in every single preview article is probably the only thing about the game I haven't submitted a bug report of any kind for.
