The members of the party are out of control for the theme but it removes the main part of the RPG battle, being just a manager and watching your party battle does'nt get fun. Maybe you should've tried the theme on a different genre, for eg. puzzle games and action games become quite challenging when some control is taken off.
But trial and failure is a part of learning... I liked that you used RPG maker and tweaked it enough to make battles automatic though.
