A lot of the stuff on the wiki is accurate, but a lot of the quests after the festival day quest ends don't really help a whole lot. There's some smaller strategies, but outside of that not much. For example, the wiki only really explains how to get to Winterfall by boat. There's no help identifying the path through the woods, the game indicates this is an option, and I assume is through the lake, but there's nothing really pointing you toward it.
