Something ASCII art

[Kwassoaughnt]

In Omori's files, there is a file named "www__for_Sunny__.txt", which is a reaction of Something via ASCII art, made with primarily 'M's and 'Z's. The pupil has the text "THERE'S SOMETHING BEHIND YOU", however. Not sure whether it is a well known thing in the community (like with many of the secrets in the files of Undertale and Deltarune). Also not sure where I should put this in the first place, so I went with the safest option, but I can't upload an image via discussions.

Yes this is well known. The file is created based on the name of your character when you get the "Other ending".
