The nice folks at GOG.com were so excited to Almost human's Legend of Grimrock in our PC Indie Spotlight they spontaneously expelled 15 codes for the full game. I'm not touching them. I don't know where they've been.
As you may or may not have heard, the digital distribution platform formerly known as Good Old Games is now simply GOG.com, reflecting the change from carrying good games to only bad ones.
Oh wait, I read that wrong. Now they carry new games as well as old ones, so Good Old doesn't quite fit anymore.
