The game is still not ready to finish, but you correctly noticed the basic concept of the game. The final version of the game will have a list of all available endings, so you can see which ones you have opened and which ones you haven't. Well, for those who really follow the game and want to see how it develops, I advise you to visit the official website and Twitter. On the site you can find something like a bestiary, as well as a walkthrough, and on Twitter new art and my posts.
