Can we know when to expect this final demo of the game to release ?
The final demo or the full game? The full game is late 2028/early 2029, as stated on the game page. We'll update if this changes.
We plan to release a demo content update closer to the end of the year, with new scenes and more art. There's going to be more demo content updates in 2027, but we'll talk more about those after the first one.
