Right let's start with what I like:
I think that the enemy army composition is designed well (even if attack waves are fairly weak in general).
Attack waves are constant enough so that you don't want both players leaving the base (not even bunkers will protect you).
And now for general comments/criticism
Was able to beat the map (and destroyed all structures) solo. 2 players shouldn't have much of a problem because 1 can defend while the other attacks.
(made an hour after the first paragraph) Yeah I played this 2-player and practically carried my teammate to victory.* Could use a difficulty upgrade imo.
One thing that should be changed is the top waves imo. Right now they have to go around the sides of the hill, and that leaves them open to a player standing on a higher level of elevation.
The zealots had a tendency to charge around the sides of my army then die before they hit something. I guess this is SCII AI trying to hit medics in the centre.
One thing that I disliked (map wise) was that near the right edge of the map you can't center on your army. It's just personal preference but I like keeping my army in the center of the screen.
If anyone needs a "temporary friend" to test the map, it's TChosen1#1560
\*Unimportant details of carrying but useful as a testament to how little imput is required from one player: Guy didn't build a combat unit until 2 minutes in, and more than 1 barracks until 12 minutes (as a comparison, I was operating off of 5 racks at that time) and was operating off of 7 or so SCV's on minerals, 6 on gas (20,6 for me) for the longest time. I solo'd the expansion defences, the big defence in the center-right, and 3-4 attack waves
