Alpha includes campaign and level editor
I'm hopeful Secrets of Raetikon will be successful for Broken Rules, based on what I've seen of the aerial exploration title. It's great, but it is also one of those games that's perhaps better experienced on your own as opposed to being told about it.
The developer has announced its Steam Early Access launch date, which is set for January 7, 2014. That could very well be the place where Secrets of Raetikon builds its initial audience. The alpha build will contain the game's single-player campaign and editor, minus the "grand finale," with an expected finished release date of Q1 2014.
My favorite part of the Steam description is the suggestion for players to "grab a robin and feed it to a buzzard." Well, if you say so.
