Well, now I've reviewed the castle dungeon quest levels and I'm missing them. Too bad I can't make a video. It's a classic raise/lower water puzzle, get's you the level 1 glove (lift rocks), a few secrets that you can bypass, a projectile boss battle, with little other combat.
Forgive the lack of relevant graphics being loaded, but the level names should be self-explanatory (this is like screenshots of a third, and all missing lots of graphics, but whatever).
