i have another petscop theory because spaghetti tacos:
i have a game theory. what if the petscop footage is all "found footage,"? like it was lost but found again by someone who decided to post it up on youtube? this could be why paul addresses the audience as "you" and says "maybe when you get home next month," like he's proving something to someone traveling. this footage could be who knows how old! it could be possible that paul is a beta tester for this game and is recording his gameplay so that when the garalina company (or rainer(maybe rainer is part of the garalina company?)) checks in on him he can give a throughout report on how it is. he probably said he had a bad experience with the game and said that it scared him, it made him uneasy. garalina took the game down due, or quit production, to his experiences, never to be actually in stores. this is probably why this is the "only one of it's kind," this game probably does exist, paul is just the only that obtains it at the moment. another theory is that this game was garalina's first game, and with this report from paul(the beta tester), they became unenthusiastic about future games, like they would get the same report, or even worse. they decided not to make anymore content/games and shut down the company. they might come out again, no one knows.
