I understand that. But when I hear Unity Base, it sounds like you mean base Unity features, not based on an Unity tutorial. I have done this same tutorial myself, and I can say that this is very similar (almost exactly the same) as the tutorial setup, graphics, level design, and the way that the game works.
Don't get me wrong; I think it is great to be working off of the tutorial to make your own game, but as long as you are using the graphics, sound, and level design from the tutorial, I would suggest citing it. Latter when you make your own levels, and own graphics, then you won't need to cite it anymore.
Here's a link to the tutorial, in case anyone is interested: https://learn.unity.com/project/john-lemon-s-haunted-jaunt-3d-beginner
