After being Greenlit a few weeks ago we've been busy getting our Steamworks account up and running, but we're finally ready to release. In addition to full controller support, steam cloud and achievements, we've also upped the overall difficulty of the entire game.
Dark Echo will be available via Steam on May 11th. Visit the store page
If there's enough interest we'd love to explore the idea of adding a level editor to the steam version. Players could author custom levels that could be played by all platforms including mobile. If that's something you'd like to see in the future, let us know!
