Robot Unicorn Attack 3 still missing

So I know that Robot Unicorn Attack 1 and 2 have been archived, but as far as I know, the third game hasn't and is still missing in action. If there's a way to find the game and preserve it l, that would be great.

Here's two videos from YouTube to prove that it does or did exist.
