Sure is. DDLC falls under the category of visual novels. It presents a story visually and allows the player to progress and influence the outcome through their decisions.
Well, start by getting really familiar with the characters and their personalities. That's key. Then think of an interesting plot or story arc that fits within the DDLC world.
Yes, there are some really interesting ones. You can find them on various fanfic platforms. Some might focus on crossovers where the characters from Mystery Skulls and Eddsworld interact in unique ways, like going on adventures together or solving mysteries.
One interesting fanfiction could be 'Vampire Matt's Hidden Powers'. It might explore how Matt, as a vampire, discovers unique abilities within himself. Another could be 'Matt's Vampire Adventure in Eddsworld', which could involve him going on a quest in the Eddsworld universe with his vampire traits adding an exciting twist to the story.
One popular theme is the exploration of the characters' backstories beyond what's shown in the original game. For example, delving deeper into Sayori's depression and how it might have developed over time. Another theme is alternative universes, like a world where Monika isn't self - aware and the club functions 'normally'. Friendship among the club members is also a common theme, showing how they support each other through various situations.
