The layout is a good start, but it's a bit too basic.
The intel room is way too big and the team that can push up and hold in the enemy intelspawn will cycle cap without much trouble.
The returntimer is much too long for such a small map.
The attack options were either: past spawn or straight to intel. Get the spawn away from the paths, somehow. Or add more attack routes.
Long sightlines lead to sniping oppertunities, might want to cut them down on the entire map, worst is the one on the second floor you can actually zoom in on a respawn door exit.
The game was really fast though, but one sided. If you can keep the matchtempo but even the chances of winning a bit/increase chance of comeback. It could work out nicely.
