Start by creating interesting and diverse characters. Make their personalities and backstories engaging. Also, come up with unique and exciting scenarios for the dates.
In a regular dating sim novel, the focus is mainly on the relationship building, the cute interactions between characters, and perhaps some light - hearted drama. However, in a horror dating sim novel, there are often threats and a sense of danger. For example, the love interests could be vampires or werewolves that pose a real threat to the protagonist. There are also likely to be more jump scares and a darker, more foreboding atmosphere throughout the story. It makes the process of falling in love a much more thrilling and dangerous experience compared to the more relaxed feel of a regular dating sim.
One difference could be in its plotlines. 'Endless Love' might focus more on deep, long - lasting relationships compared to others that may be more casual. It could also have unique character archetypes that set it apart.
One of the best is 'Doki Doki Literature Club'. It has an interesting plot that initially seems like a typical cute dating sim but then takes some unexpected and thought - provoking turns. The characters are well - developed, and the writing style is engaging.
First, you need to come up with an interesting story and characters. Then, decide on the art style and graphics. After that, program the interactions and choices for the players.
Maybe it ends with them realizing they're not right for each other and going their separate ways, but still having learned valuable lessons from the experience.
