The map (don't know the original) looks pretty good, but not perfect, might require a minor update or two to get there.
Some lights, mostly near water tanks upstairs, are extremely aggressively brightly white in a way that doesn't seem intentional or fitting, might have to be toned down a little bit.
And there is at least one spot with a broken, purple/black texture (left-side below the "Aquarium ⭐⭐⭐⭐" sign at the end of a hallway near middle, close to the wall-mounted sign saying "Reverend Guppy's Aquarium" and a security camera). Didn't see any other.
Overview works, but nav file is missing, and consequently, so are place names. Didn't test gameplay.
