Hi Midichat,
Unfortunately, this game is episodic. Meaning, it's like a tv show instead of a movie.
The end may take a very long time to come (years), and the game already has way over 10 hours of content for each route. Furthermore, due to having an active community and support, the game's initial 6 episodes per season has changed to 12-13 episodes or more.
So, if you personally prefer movies to tv shows, this is definitely not the right game for you. 🙏
