Hi, Oculus People. Below you'll find details about getting the game. With either version, make sure you enable VRMode in the options window on the title screen.
If you're a Mac user, there's a well tested version up on the Mac App Store.
There is now a Windows version. It seems to be working well, but it is still somewhat untested compared to the Mac version.
If you like the game, it would be amazingly awesome if you could vote for it on Steam Greenlight.
