Just Ok
Of the four game book adventures. This is the third best one. It is ok, but not great. No major problems, just not as entertaining as you might hope.
It does have some interesting combat sequences where you make choices instead of roll dice. But overall it felt a little small. Even though you travel in boats, are captured as a slave etc. It just felt a little constrained. Like you had two or three parallel paths to choose from, and you cannot find the interesting one.
