Not all of it is based on true stories. It's a mix of fictional elements and possible inspirations from real-life incidents, but it's not a straightforward documentation of actual events.
First, you need to have a good story idea. This is the foundation of a visual novel. Then, create the characters, design their appearances and personalities. Next, you can start writing the script, including dialogues and plot development. For the visual part, you can draw the backgrounds and character sprites yourself if you have the skills, or you can hire an artist. Also, choose a suitable game engine like Ren'Py which is popular for visual novels. Finally, add music and sound effects to enhance the atmosphere.
Some cable channels might air it. You could also look on Amazon Prime Video. Sometimes local TV networks have it too. Do some searching on these options.
It's a festival related to fiction. It might be a celebration of fictional works such as novels, short stories, or perhaps fictional films and shows. It could be a platform where authors, filmmakers, and enthusiasts come together to share, promote, and celebrate fictional creativity.
Since I'm not familiar with this particular graphic novel, it could cover a wide range of themes. It may revolve around the dentist as a central character, showing their work - life balance in the context of their home. There could be stories about the history of the house and how it became a dental practice. It might also depict the community around the house and how the dentist and the house are perceived by the neighbors. It could be a story full of human interest, with the dentist's house serving as the backdrop for all kinds of interactions, emotions, and events.
I'm not sure. It depends on various factors and how the story was presented. Sometimes stories are based on real events but might have some fictional elements added for entertainment.
Not having read the graphic novel, it's pure speculation. The main characters could include the dentist, who is probably central to the story. There might be a nosy neighbor who is always curious about what goes on in the dentist's house. Also, if there are any apprentices or trainees in the dental practice, they could be main characters. Maybe there's a patient with a phobia of dentists who has a character arc throughout the story.
