A lot of games and projects spend forever in development because the team involved have bitten off more than they can chew. In our case, there's only 2 of us producing content for Sileo. We don't want Sileo to spend forever stuck in limbo - our hope is that Sileo will reach version 1.0 within 2 years of it's original public release, and so far, we're on track for achieving that! Unfortunately, in order to achieve that, our development scope must align with our manpower, which is largely why we've sacrificed complex branching routes for a more linear experience.
We're glad you enjoy it otherwise, though! Development on Tai's route is underway and will be coming your way soon!
