I was doing the tutorial for calibrating work spaces. I chose the knights thing, I assume the tutorial wanted me to choose something with three upgrade slots and not two, so it couldn't go forward because it wanted me to spend all three before the tutorial would advance, but I could not, so it was a soft lock. I'm just speculating on that one, but it makes sense to me. Otherwise, great game so far. Keep up the awesome work....

what's going on? is the development still run nicely or not?

especially on the factory and spell building mechanics, is there any tutorial for this? or video explanation or something like that?

I was endlessly confused and I didn't enjoy feeling confused. The demo itself is really good, I could use a bit more "...and this is the point of what you're doing" though

Loved the setting and combat. I do have some minor gripes. The first is that I didn't realize you could put more than one spell into a department, such as the ground shifting department. Some clarity here would be nice. The second is that it would be nice if the effect each policy has shows up in the dialog box when you hover over it....
