We’ll occasionally drop DLCs like Halloween that will be released as main game episodes during development. When the game is finished, we’ll gather all DLCs into a separate game consisting of chapters.
There will be at least five: Christmas, Halloween, Prequel (about childhood of the characters when humans arrived), Naira’s fantasies (unusual scenes like in the city or gangbang with fans - made as her fantasies during masturbating), Erection day (probably it will have an orgy with all the girls).
Also maybe more, like doki-doki parody, about Naira’s ancestor, or the horror story. Halloween and Prequel are the most scenario important.
