Secrets of Rætikon, the beautiful spiritual successor to Chasing Aurora, will launch in full next week.
Developer Broken Rules will move the project from Steam Early Access to full launch on April 17.
The Linux, Mac and PC title will be available for £7/$10, with a 10% discount for launch, through the Humble Store, Steam and the Mac App Store.
The Steam version includes a level editor and Steam Workshop support.
From the same team as And Yet It Moves and Chasing Aurora, Secrets of Rætikon has players exploring the ruins of an acnient civilisation. It's an open sandbox, but there is a narrative, and you'll need to draw on the abilities of the animal friends (and foes) you encounter) to progress by solving physics puzzles.
