Try giving credit to the original mind behind this idea, aka me.
I don't know if your the "original" mind behind the idea. I see your post above with the link, but there's been a lot of gravity related suggestions. You're probably not the only one who thought of this. For example- many many people, including me, have asked for the gravity playertype. This isn't that different.
Anyways I doubt this is possible without something like the gravity playertype- which doesn't exist. Unless You want this to be somewhat less like super mario galaxy, and pull you, but you'd always be right side up.
