Yet, I think the Backrooms-styled levels/games are not exactlty for everyone, as some people might just see it as a big nothing. Let alone the fact that this kind of things can be found disturbing or shocking (by the way, for really good reasons).
Still, for me personally this level brings a lot of fun, as it gives you opportunities to regulate your own play style — it can be both fast or slow, depending on the number of bots you add. Some maps are only intended for fast gameplay, some are strictly slow, but this one belongs to a different category, because it gives you a choice. I think that is rather common for well-made levels with labyrinthine nature.
