"Black Border Simulator Game is a great combination of papers grade please games" makes it sound like they know about the similarities. It looks like the trailers have the same ideas in the same order. Is "it's a knock off" enough to do anything?

Looks like they've taken some assets directly from the website Tumblr too.

It looks like there are a few more reviews from people who have [DNA] at the start of their account names. Other positive reviews do note that the game needs a lot of work.

I downloaded the Android version of the game. (It's free on mobile.) I was only able to finish the first bit of the game play, but I found several unlicensed band posters in the opening room.

It seems like the music used in the trailer is licensed from some place. Putting it through Shazam shows it's the same as the opening seconds of this Polish video: https://www.youtube.com/watch?v=O5JiLioDqgI
