The Nightmare is popular for all the wrong reasons. It is probably closer to 8 stars than easy demon, which makes it baffling how it got rated demon in the first place. As a result, this level became one of the most popular levels of all time simply by being one of the easiest demons out there, a perfect “free demon” for beginners.

That being said, the level isn’t that bad, especially given how old it is. The ball parts are pretty unique for their time and this is one of the few levels that uses the mirror portal correctly. The triple speed part at the end is a bit out of place, but otherwise the level flows well and is pretty consistent.

If not for being an easy demon, this level probably would have been forgotten, but it is still a good look at early Geometry Dash and there are much worse levels that could have taken its place as the easiest demon.
