"Ready when done" will always be my answer. More time spend on project only means that it gets better than previously planned.
And oh boy, this one is huge, recently it got much bigger than I planned, actually it's gonna be my dream game.
Additionally keep in mind, I'm planning to finish Leaden Sky: Nightmares soon so I'll be taking a break at least for a month, but I'll be back to working on main game as soon as I'm done.
