Typically, an ordinary creepypasta visual novel often has a dark and eerie atmosphere. It may involve strange and disturbing storylines, like haunted places or abnormal characters. The art style usually complements the spooky mood, with dull colors and shadowy visuals.
First, come up with a disturbing concept. It could be inspired by nightmares or existing horror stories. Then, focus on creating a unique setting, like an abandoned asylum or a haunted forest. Sketch out your characters with their own quirks and secrets.
