Right now, the only video content is a tutorial...Granted, Vince and the Wadjeteye crew were kind enough to already provide in-game commentary, but I'm just wondering if there's more vids planned.

The GoG version should have come with two or three dev diaries and a behind-the-scenes look at the voiceover recording sessions.

Dave: I've got one MP4 file called Resonance Developer's Diary Supplemental (which is the short tutorial) and one FLV file called Resonance Developer's Diary Supplemental 2 (...? Can't play that file format).

At any rate, thanks for including the soundtrack; I have that hospital theme stuck in my head. Annnnnd the game's fantastic!

You should be able to play FLV. Just open it with your media player, or just rename the filetype to avi. I use WMP Classic with the CCCP for codecs.
