Just to clarify, the storylines for the main girls will mostly be self contained. So when I say “finish the project,” I don’t necessarily mean wrapping up all 12 of them. It could just mean fully fleshing out Leah’s story and giving it a proper conclusion with multiple endings.
A common criticism I see is that the game still feels like it's in its infancy stages, but the truth is, it has around 12 hours of content already, and if I add another 15–20 hours, that should be enough to complete Leah’s arc. And the overall game length would add up to what I would consider a respectable 25-30 hours long experience.
The only things left hanging would be the side characters, but their stories can be expanded later on with the introduction of new girls in future updates.
