The TEACHER'S THEMES AND SFX
The teacher actually has a few unused tracks and SFX in the files. For the music, there are some different versions of her theme, like the first audio file, which would play before the vent chase sequence. Despite sounding very similar to another track that does play in-game, this specific version is still unused. She also has some unused stingers unnamed in the files and a track that i always assumed to be an old version of her introduction's theme (513897329) Which is made out of a loop from Spitfire Audio ALbion IV Uist. About SFX, there are some of the teacher eating an apple, which she never does in-game.
OLD RAINCOAT FINDING THEME
Both in the files of the demo and the files of the final game, there are different versions of the track that plays when six finds her raincoat. The first one is clearly the oldest version, as it's in a different key and way sadder. Now the other two audio files are closer to what we got, but more suspenseful, as the actual melody is absent. This specific versionn is still used in the Little Nightmares 2 Digital Comics, but it's not in the final game.
