1. Yes, we do plan an end to the game. We plan to do acts to the story, and once you finish it all up you will be able to get endings to the girl you "choose" to end the game with. It's not something we plan to do soon, since we want to fix all the stuff that is currently subpar. But we definitelly thought of doing a proper "Roll the credits" type of thing.
2. We're currently in the process of creating a storyboard for Hanako, Part 2, so we can absolutely promise to do more with her, MC, Haru and Ryuji! Stay tuned for our Roadmap updates <3
