You're actually somewhat right. Andre and I were talking on twitter at the time and also at the time I was working on an update to the mod, so I decided to let him try it to get the audience reaction. Unfortunately, shortly after that life things happened so I wasn't able to get back to any of my other mods and finish that version of SZ, I was only able to make mundane updates/small mods that took a short amount of time. Now that I'm getting a bit more free time I've decided to give it another shot. Although, making it has been pretty boring, and I haven't touched the script in a couple months (I've been working on developing a game instead).
Anyways, there is no version of this mod that exists anywhere online. Only on that man in the video's hard drive.
