Still very new. Could not get the Mac client to work well at all, though that may be due to my lack of experience with it. However, it should not be that difficult to use. Probably works better with some sort of VR rig, but again, documentation should tell me that. Documentation is poor. There is one google doc that is pretty much just an outline. There are 4 youtube videos. The Wiki is also pretty barebones right now. Relies on Unity as the base. Support forums exist but are lightly used.
