Not sure if the map that came with the game is a rough approximation if the game map, if I just really suck with maps, or both 😂
The map is pretty accurante, although it does work with screens which can be a bit tricky to see in the game where does the screen end and start.
As for your skill in using them, that's something else :P
Horizontally, the map is pretty accurate. But vertically, the map has been stretched out a bit. One in game screen can count as 2 or sometime 3 squares on the map (vertically)
