Found a strange glitch in the language level. If cleany is able to push you against a wall, you will clip through it. I even have video proof:
Yeah, that happened to me once when I was solving a notebook. Suddenly I found myself in the hallways and then I got killed by Marzia.
If you could manage to do this after the 10th notebook, you could theoretically get a view of the whole map, including any secret areas we haven't found yet.
