I'm thinking that this film (despite the idiotic name) just 'might' become a cult type thing like Rocky Horror Picture Show - just maybe?

I doubt that very much, considering it will more than likely never get a theatrical release and just about no one outside of pinball circles and people involved with the film will ever see it.  Unless it gets to a decent festival, does well and somebody of actual note in the industry picks it up for a wider release, that is like winning the lotto in film terms.
Then of course it has to be good and this does not look good at all.
I haven't seen short films in the cinemas since the 70's-early 80's.
It would have had more of a chance as a feature with better actors and a better plotline.
