it sure help if you can mix various tilesets to get what you need :) , plugins are good too :)
to me it looks really difficult but your doing good :)
i met another error , this time with the innkeeper character ,it looks like he does not have a battler sprite and since he stays with us like the hunter girl i cannot go further because there no way to avoid every battle (he does not have either a character face in the menu)
i hope it won't be a bother to fix
