We will be updating the Steam version so that you'll be able to play it properly on your CV1 Rift as well, it's just going to take a little time because all our focus has been on getting it ready and working on Oculus Home. In the meantime though, if you can't restrain the urge to support us hard-working devs who spent months getting it to a highly polished VR state, by buying it also on Oculus Store, I promise we won't hold it against you.
