The theme is average, being a mix of a Black Forest map and a Salt Marsh map. The mix is cool, but does not really set it apart from the maps that shipped with the Vanilla game, thus meriting a 3.
Visual Appeal: 2
The design is nearly exactly the same as a normal random map, which thus merits a 2. The entire map is Grass 1, Shallows, and Forest terrains.
Essentially a mix between black forest and salt marsh, the playability has high points, due to the interesting mix of gameplay styles. The number of relics in the middle assure that there will be battles over them early and the gameplay mostly revolves around them. All in all it is a fun experience but not much sets it apart from a normal random map.
I suggest that the author do a little work to improve the map design and make the map more unique. As it stands, it is quite similar to a normal random map.
