Hard to know what to say about this one. It's more of an experiment than anything else. Mapmaking at times is beautiful... but there are a number of problems with the map (some delineated in the readme), and finishing it can be very difficult. (I never did find a save term, so when I got stuck in a poly well into the map, my only choice was to quit and start over... very discouraging.) Still, there is quite a bit to look at here - if you're building maps, this is probably worth a run-through, just for ideas.
