Alright, I think it's time for my 2 cents. Firstly, I think you should do away with the items placed at the start location, they remove the survival asepct of the game, which once was a major part of the Ice Troll games. Secondly, I would add extra trees to the areas on the edges of the map, from the minimap it appears that you simply stretched the camera bounds without adding any extra content, adding extra trees would make the nex areas look more like the rest of the map. From the short time that I played, I noticed one spelling mistake, when placing spears in the tower, a message appears saying (roughly) this: "The tower will shoot spears at enemys", it's actually spelt enemies. Personally, I would remove the name "Ipwnuall" from the list of troll names, I know that it is a reference, but it doesn't exactly fit in with the rest of the names. I, for one, have never liked leveling in the troll games, it makes the maps descend to a flurry of fighting creeps to give one team the edge over the other. You made the map, not me, so you don't have to take my advice, it's your descision, though I definitely recommend removing those starting items.
This map has the potential to be good, just don't lose sight of what made Ice Trolls brilliant in the first place.
