Well, one key feature could be the unique characters from Undertale being part of the dating sim scenario. Their distinct personalities add a lot of charm. Another might be the visual novel aspect which usually involves interesting storylines and dialogue choices. The art style is also likely to be a feature, perhaps maintaining the charm of the original Undertale while adding a romantic or relationship - building element to it.
The main difference is the focus. While the original Undertale is an action - RPG with combat and exploration, the dating sim visual novel is centered around building relationships and dating. In the original, you might be fighting monsters, but in this version, you're trying to win their hearts. Also, the gameplay mechanics are different. Instead of battles, it's more about making choices in conversations to progress in the relationship.
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.
Start by creating interesting and diverse characters. Make their personalities and backstories engaging. Also, come up with unique and exciting scenarios for the dates.
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.
