I have recently finished Wes' route, and man that was wowee.
But anyways, beside that this might be a stupid, (or strange) question considering sources are already provided, but what are/is(?) the soundtrack present during the main menu, and end credits?
Viewing post in In Case of Emergency comments
Main menu theme is Komiku's "The main reason we are here," and the end credits is "The only reason we end here." Would highly recommend checking out and supporting the artist! https://chezmonplaisir.bandcamp.com/album/a-tale-is-never-forgotten
