Check the Source Files page for the most recent download. Meant for developers to use during testing. Still porting behavior. I expect a 'for play' tech demo once player movement, health, and energy systems are implemented. I also created a thread where I post release notes in the source forums.
Just thought I should put this up in case anyone is wondering what's up. The holidays have been eating a fair amount of my spare time, but I'm pushing to have some footage and perhaps another tech demo around new years.
