The Nine Villages is a quest by Obake-san. Interesting how he managed to merge the Zelda 1 and 2 worlds into one quest, while keeping the map and all pretty much accurate, just really expanded out from the original versions. This is one rather long quest to say the least, but it does flow fairly well, and the difficulty is pretty fair overall. Lots of midis used in this quest, some from old games that I haven't played for quite some time. So as you pay attention to the maps, note the similarities to the original versions. The overworld warp system is also rather neat, as it's like a zoomed out version of the main overworld, and stepping back into the warps almost likes zooms you in to that area.
Part 1 - Sucks starting out with only 2 hearts, so a little caution helps. Have to pick up some supplies before heading to level 1. And for the cave, can't have Zelda 2 map references without some Zelda 2 tunes in there.
