Maybe once the whole main story is done, you can keep interacting with different characters, like more dates, saucy stuff or just doing whatever, maybe an adventuring minigame with the fox (i forgot her name), or daily living stuff, an optional "survival" mode, in which i mean a hunger bar, cleanliness, etc. to keep people engaged. i mean fr tho, thats what good game-makers aim to do, increase engagement.
For sure! At the moment, I would like to make a more linear game with minor branching paths (like what was seen in the current version) since I want to it to feel like a story as well as a game. However, I will try and incorporate more 'minigame' stuff in the future once the main story has developed enough.
