Just came to vote 'no' for this game.
The devs have engaged in some pretty scummy behaviour as far as I can see. Their Kickstarter clearly lists the game as being DRM-free, but once they got Greenlit on Steam they made the game Steam only and in doing so effectively abandoned the game on Desura.
EDIT: It gets worse! They claim they only use Steam as a distribution system and don't use Steam's DRM. When I pressed for clarification they said it has to be run through Steam. How is that not using Steam's DRM?
