I haven't checked it out since I don't have sound at work, but apparently it shows gameplay with voice-over from one of the devs.
Of course, said voice over in a previous trailer nearly made Ivan & Gordo lose their respective lunches (something about how faithful the game was to 3rd generation D&D rules...I think it overloaded their geek capacitors), so you may want to approach with caution.
As a bonus, I think I've found Gordo's dream game....thank me later, dude. =D
