+1 for linux. If anybody has Unity installed it's dirt easy to just run a build. Source code is here: https://github.com/keiwando/evolution Of course, it would be best if keiwan did the build, but at least this way we can get a build.
I just released a linux version with the latest update.
However, I won't be offering any linux specific support or extensive testing of this linux build because I don't have the resources for that. Also as a heads up, there is a bug in the current version of Unity that causes every keystroke into an input field to be registered twice in linux builds [see here], which is quite annoying. I'm probably going to rebuild the linux version once they fix it.
