The lighting indicators and hyperlinks were well appreciated and the maps look great! There's a fair number of spelling mistakes that were a bit distracting and I think areas B8 and B9 are mislabeled on the map.
Overall though I really liked this and the image of a great green walls standing against the tide is very evocative. Being able to possibly communicate with the Children of the Sea and not just hack and slash through is also a big plus.
