Was not able to get very far with this. I couldn't work out how to defeat Mitchell. Despite reclaiming her bag and healing items, the option to access them was not in the battle menu, so I had to give up after getting a game over 3 times.
I think you might have a save bug as well. I noticed that you'd accidentally left a save file in your game, but starting the game from new actually wipes this out. That also means it wiped out any saves I'd tried to make since I didn't want to keep talking to the npcs whilst trying to change my strategy and see if I could defeat Mitchell. (I grant you that I'm not a fan of turn based battles and so don't have much experience with them, but it seemed a little off.)
Unfortunately that's the only real feedback I can give since I couldn't get far enough to get any sort of impression from the story. It was nice that your npcs had personality. Wasn't overly fond of your title screen graphic or the use of the medieval tileset alongside the rtp though.
