From what I've seen, this looks like a fun game.
I'm experiencing the "flailing around" glitch and don't know how to fix it. Can you make another video with instructions for us Linux users and Mac users? The only Windows computer in my household is my brother's and I doubt he wants to dive into System 32.
Also, I've noticed that I'm never able to log in after logging out. I've created about five in-game accounts now because I've been unable to log into any of them.
