I like the updates and the huge roster of ghosts and minis you can encounter.

Players who bring up Graphics mostly praise it.
15 of 300 sampled reviews raised it
It really is a shame too because the art style is great, the characters visuals are fantastic the maps are awesome for the most part(not a fan of the first houses 2nd story layout) I like the mystery inc feel I just wish it leaned more into that, instead it's just a pretty confusing mess of ideas with a great art style.
