Actually the fight was fine with just Sadie, I think the one with 5 opponents was a bit rough, but overall it's doable.I appreciate the feedback, thank you. In the next release, I am shortening the length of the first battle and making that fight in the castle a little easier. I do want the game to be challenging like a classic RPG, but I did admittedly scale the castle fight for having two characters in the party, so I'll think about what might help balance things best in the single-character party path.
Having that Goblin would probably make it a walk in the park, maybe you should have the little guy removed before we get there so you can balance this fight properly.
