Critique and Advice; the treadmill of adventuring.

Don't stop! It's good so far! Most of the things I wrote were just advice if you do another adventure, or for later updates, and you even fixed some of them. The textboxes, for example. Initially I was a bit worried about them, but now that I've gotten further in, I've gotten more used to them, and I even think that they're an important part of the story.

From personal experience, the worst thing you can do to an adventure is try to start it over. It doesn't work. Ever. Especially since what you have so far is already so good, I would just focus on keeping things moving in later updates. Don't worry about the older stuff.
