Definitely no. It's the default Unity scene for the new version of Unity game engine. I was sure to include this on the game page right from the start: "NOTE: The play area is just the test scene from Unity 2018.2, which I did not make, but I did tweak it a bit. I don't deserve any credit for how good it looks. If it looks bad, though, I probably broke it somehow. You're welcome. Other credit: ball texture here."
