tested the game unfortunately it needs more improvement, 1.76mb is too big for a melee map I look inside and spot unused imports that's why you take too much file size, looks like you forgot to clean the map based from the HC#6 template you made am I right?
also I suggest the player limit to: 1v1 because the map is too small and the destination for all players are somehow stick to each other and else. this can cause a game situation problem among players that are not allied or probably playing FFA, remember the error what Ice Crown(RoC map) did to their team locations
the blight tile is meant for UD players, that tile set is not meant as a decor but more of a strategic application for the undead(blizzard also made an item for it its called "Sacrificial Skull" it releases a blight ground around the caster)
the trees near to team base is rather few this is an important resource also the map's concept is Anshenvale getting some sort of invasion of an entity probably orc, demon, etc. so the landscaping should look like ashenvale forest with smashed out enviroments and stuff, and finally the use of the Goblin Laboratory is it meant for the fountain of power? probably yes that is kinda inferior to a small map how about just make a small ramp for players to go in and make up a strong or moderate level creep/s guarding it, also not sure why you also have to place a way gate.
overall the map is cool but since your main objective for the map is 'small yet approving' find useful tuts about melee maps, or for some quick view look into 2 player maps hope you can understand, good luck with the updates
