PONG, but is a horror game

My friend and I are seriously considering developing a full-fledged horror Pong game. Literally, one afternoon we got together determined to make our first game in collaboration with someone else, but first we had to define the main concept. I don't know how the words "Pong" and "horror game" came to mind, and I thought: What if we made a horror Pong game? It's kind of weird: how could such a basic game be scary?

Anyway, we ended up liking the idea and embarked on a journey to develop a horror Pong game for a month (which ended up being two months). In the end, we only managed to develop a demo that has just a very small part of the original game. We ended up making something like FNAF 4, but with Pong as the base.

We'd like to know if there's interest in this concept so we can fully develop the game, as we initially planned, or continue scaling it down little by little, like we did at the beginning, haha. Does this concept appeal to you? Is it something different, or does it not pique your curiosity at all? Should a game like this exist, or not?
