Does anyone have a connection to Terraria: Otherworld?

I know this is a long shot, but I'm looking to obtain a build of Terraria: Otherworld. I'm willing to pay handsomely and agree to not speak a word about the acquisition. That is to say, no posts, screen shots, videos, or anything whatsoever publicly or privately, to any other party. I can prove I'm good for the confidentiality if need be.

For those unaware, Terraria: Otherworld was going to be a follow-up to Terraria; however, after a few years of development, changing studios, etc., the project was cancelled. I'm a huge fan of the series, personally, and would like to acquire a build (or more) for my own private collection.

Thanks!
