Sorry, yeah we will have Gravi available on Mac & Linux hopefully by the end of February. We had it working on Desura on Mac & Linux, but when we moved to steam it broke.
I'll keep you updated as to when we get on the other platforms.
Thanks,
Sounds like you should hire a full time Linux developer, steambox/steamos is the future. I'm graduating with my CS masters in May, and I'll be available in August.
But, hey, thanks for keeping me from spending bitcoin on a game I really don't have time to be playing. I need to help automate my schools mining robot for the NASA competition and finish my thesis on classifying web content based on semantic content and link information. It is quickly becoming a busy semester.
