We're waiting on a response from itch.io, but it should be soon!
Oh no! Unfortunately, we didn't set up a graphics menu, but I might be able to push out an update where you can change the graphics for the museum. The main reason why is because the basement section is unplayable at any of the lower graphics settings (it basically breaks the lighting, and you can't tell where the Demon Peepachus are, resulting in MANY game overs)
