I liked what I played of this so far, but I seem stuck due to a game-breaking bug. On Windows 10, the game sometimes throws an error when saving, and attempting to load from the main menu causes the game to hang.
Placing the confirm and cancel buttons so far apart is really awkward. I'd recommend using the RPG Maker standard of Z for confirm and X for cancel/menu on QWERTY keyboards, or making the buttons customizable.
Curl seems incredibly overpowered because the items it steals persist after battle. I spent the first chapter stockpiling items, and by the second I had more than I knew what to do with. (It might also be a good idea to make it clear that items stolen by enemies are refunded at the end of the battle.)
