This game is absolutely beautiful! The visuals, the music, the atmosphere, and the writing is incredibly well done as well. Can't wait to see more from Oko.
Why does the game have the completed tag though?
Because work has stopped on it.
Pretty sure Oko can answer this better, but I think they just didn't feel like finishing it, didn't like the direction, or just couldn't stand to work on it anymore. Or maybe they just fell out of love with it. They have a post on their blogspot somewhere regarding it.
It's a shame, because I would've loved to have seen more scenes with Stace, since it seems only her Storyline needed a bit more, but it's whatever.
They haven't dissapeared off the face of the Earth, and they have tons of other neat stuff. So it's cool in the end.
