Excellent work. did you make the map yourself? is there a version available to print for a physical copy of the game? I much prefer it to the alternatives.
A .ztb file can be read by zuntzu ( a cool virtual game board tool ) but it can also be read by unzip/winrar/7zip. Inside the .ztb file can be found the map as a .jpg file and some other files needed by zuntzu to use the game module
