Progress on the demo is a bit all over the place -__-
The problem is, unlike something like Kurovadis this is game is a bit more non-linear in some respects, so It's difficult to decide exactly how big the demo should actually be. Stages are shorter but more numerous in this game, and there's a lot of acquiring spells or items that allow you to get to smaller areas within previous levels.
The progression and feel of the game kind of depends on the idea that there's stuff to find, and little events you can trigger rather than just moving forward through stages constantly. But trying to achieve the same feel in the demo means that it will take longer, or might cover too much of the game, giving the player the impression that there would be a lot more in the full game, when there isn't.
When you look at Eroico, it's 3 levels, and level 1 is the demo. It would be like that, but if there were also things you could do at any time, so how much of that content do I include? Hmm.
Anyhow, back to work, not gonna make any progress just talking about it...
