The map stinks. The rules are problematic.
OK, let me explain.
I designed the map, but it ended up being printed (quite beautifully) on really thin gloss paper.
The rules were hyper condensed onto two sides of an 8.5x11. Some stuff quite literally fell off and didn't get printed.
So, with the game now available for $20, you should download the core rules, use those, and either use a plexiglass map cover, or any square grid map from any of a dozen other games. Or, of course, the original intent of Nin-Gonost terrain.
