A small crew has been sent on a galactic voyage in search of habitable planets / intelligent life. Unfortunately, a mechanical error has left them stranded. "What do we do now?" the crew asks. The captain steps up and deploys probes to scavenge nearby planets, and decide whether to take the crew home, or continue the mission.
Unity 5 b18, used Mixamo to build characters (but don't worry about that 'cause you won't see them), FL Studio mobile and BFXR for sound/music, GIMP and blender for art assets.
Unzip the Instalers.zip folder, then run the appropriate executable for your operating system. (Supports an untested Windows, OSX, and Linux).
Sorry, no web player this time. Found out at the end that Unity 5 beta doesn't support sharing web player builds. :(
