I'll just be writing down what I think as I'm playing through the demo:
1. Meilia is in my party before I find her at the Inn.
2. Your mapping could use a bit of work. Mixing tilesets like that is kind of immersion shattering, but maybe that's just me.
3. Those Demon Guard could use some varied dialogue.
4. In the Forest there's some tiles that should be on the fringe layer (meaning should be rendered above the character and passable) that aren't, such as a dead tree's canopy.
5. Several spelling mistakes exist in dialogue.
All in all, just lacking general polish. A good start to what is sure to be a fun little timesink, though!
