Interesting... I download it again see if this changes the Level 12 to 13 load... This is the Level where you are in a Box surrounded by Ghostgirls, each of them in a corner with color.
Than after you pass one them you will hear Whimpering and a door unlocks, behind that Door you get one Pic and a Deadend, After that at least that´s how it should be, this was most likely a Timetrigger after a while you get the Otaku Killer pic and the Level ends, But this did not happen for some Reason, nothing what I did mattered, run through every Tile of the Level for 10 Minutes but the next Level didn´t load. I repeated this a bunch of times which did nothing to change that. .. maybe did I break a Trigger somehow by moving too fast??? Don´t know.
Here is a clip from it: https://drive.google.com/file/d/1nQdQT7YVDlOqAcxnHYboBzMFQWGpFv8v/view
