Well, this game is still in need of some working seeing as how this episode ends with me discovering a game ending bug.
While, I don't show it in the recording. I actually spent about another forty minutes on this game. Seeing as how the developer claims the castle and whatnot are of limits to lower level characters I decided to push myself up to level 10 and see if if would make the barriers disappear. And the answer to that question is resounding no. So far as I'm aware the current version of the game is actually unbeatable.
Thankfully, it was possible to beat this game by transferring my save file from the second version of the game to the original.
