Runner 3d Demo Release 2 Should be available on 3/26/2013! As it said on Demo release 1, this newer version will include an options menu, an entire new world to explore, and what we have all been waiting for, 2 player co-op! Don't forget to download it, as a Mac and Linux version will be out as well! But Until then, enjoy all demo release 1 has to offer by downloading it on the downloads page (if you haven't already).
