The game was released on October 30th, 2016 for Halloween. It was showcased in the video, "Yanderetale Genocide Route - Oka Boss Battle" on YouTube.
- Yanderetale is the second game released by YandereDev for Halloween, after Yanvania: Senpai of the Night.
- YandereDev originally had bigger plans for the game, but restricted himself to working on it for only 7 days.
- Yanderetale has as much chance of becoming a full game as Yanvania does, but it would have to wait until after Yandere Simulator is finished.
- The music that plays when fighting Oka, "BAD TIME", also plays during Bad Time Mode.
