Last year at E3, Cleaversoft introduced its not-so-endless runner, EarthNight. The beautiful hand-painted art gave us a look at the world from atop the backs of dragons.

The title was originally scheduled for release this year on PlayStation 4 and Vita. Unfortunately, the team is looking at a 2016 release now.

However, we do get another trailer and a better understanding of how EarthNight works. Players will alternate between a free-fall segment and running along a dragons' backs as they endeavor to reach the surface, representing the final level, EarthNight.

Each of the dragons is procedurally generated, but with bits designed by hand. Rich Siegel, Cleaversoft's lead developer, says that the first world alone has 244 million potential configurations based on the different chunks designed for each of the four dragons. 

Carrying that through to a complete game yields 6.93 x 10^39 permutations. So, despite the procedural elements not being truly limitless, it's unlikely you'll see the same exact run twice.

EarthNight is running on Unity 5 and will be 1080p and 60 frames per second when it launches in 2016. You can read more about EarthNight in a discussion piece from E3 2014.
