It takes a little longer than I expect to prepare materials for Steam GreenLight, mostly the Trailer video. It's not easy to pick a proper track for the BGM. I wanted it to have strong rhythm and varied tempo during 90 secs. Vivaldi's "From the new world" is quite fit for this purpose.
The result video is "Trailer-1" in the video section, you can also see it and many new screenshots on the GreenLight pages:
