There isn't a trailer available, so have this 'podcast' with Mike Bithell & Alexander Sliwinski describing the game (it's at 1m52s in) : Blurb: When the truth is buried, go underground. Step into this new take on text-based adventure from the award-winning team behind Thomas Was Alone and Volume. A short story that hands you the fate of the world above, as a detective looking for answers on the Subsurface Circular. My friend did the music, so I'm biased and think you all should pick this game up It's out on Steam and is 20% off until August 24th, so you can pick it up for less than £4! It is a very short game though, around 2 or 3 hours long. But a Bithell game with a great soundtrack for £3.84? You can't go wrong!
