It is recommended to watch it only in 720p. The footage was recorded in 1366x768p resolution.
This "TV-style" gameplay video shows new things in the game and its locations (not seen before ones included!) in their current state (December 14 2013). You can see some improvements in the first level over the November 14 gameplay video and about 9 more locations.
Perhaps I will post some guide for all locations in the game later, there's a lot of background information about each of them.
You can also watch this video on IndieDB and Vimeo.
