No, this is just the demo, the one on Steam is the Early Access version of the full game.
Well, I wouldn't be mad if Hakita decide to put an early access builds also here. Unless putting a files here generate more problems for some reasons. For now it seems that we will got a full game in 2022, so it takes some time. I don't want to bragging too much about it, I understand that steam have a much, MUCH bigger community and from pragmatical/financial point of view it has more sense to focus on this platform, but still..
