Hi! Unfortunately it is very likely that it won't be out so soon, since we plan on adding so much more content than we originally planned, a more correct estimate is Q3 2026 at least :)
It will likely be paid, but this is still not our demo yet, we plan on adding more free (demo) content, once we reach a point in which we are okay with the amount of content in it then we will release the actual demo of the game :D
