Finally, someone that knows how to put out a demo :)
Nice art, Good music.
Overly talky in parts (mostly during combat), but mostly understandable. Biggest issue seems to be a slow transitions between lines and the green arrow isn't very responsive when clicked.
Battle system is pretty generic, took me a bit to realize when buttons had been clicked (sound cues plz). Didn't catch on to the washed out monster graphics was the one I was targeting until multiple enemies showed up. I think it'd be better if you gave it a more clear indicator (like highlighting/aura effect or making the selection get slightly bigger to make it pop out more). Basically the UI is a little weak, visually.
Overall a very good demo and a good starting point.
