Why did you place that message so far away? I hate it when you've obviously won a map and then still have to fight a long way.
But for the rest I liked the map, it's like you said easy but still offers a challenge. Also I like the accurate map of the Netherlands, but it seems like you've already drawn Easters and Western Flevoland who were only created in 1957 and 1968, while the date of the flood was 1953.
EDIT: Forget about the Flevoland thingies, didn't read the description right.
