I would love to share some! I'm hoping to get some made for both this game and Sleuths, maybe over the holidays.
In the mean time, the videos on the first edition are still fairly applicable. The big change from what you see in the first edition game video is that the new version removes the reliance on the web app to generate the missions; most of the underlying mechanics remain fairly similar, but the interaction with the dungeon environment has changed significantly as a result (for the better, in my opinion).
The video about assembling the papercraft is still entirely applicable with no changes.
