Cool map. Strong design fundamentals here. In an attempt to gripe, the HMG "area" might be a bit of a stacked location, but this isn't necessarily bad.

One thing that may hold it back somewhat is that the map, generally speaking, is quite wide open - most rooms feel roughly equal in terms of available "play space" and most engagements will be at mid to far distances because of this. Chokes will sometimes force closer range fights but they're very wide and easily cleared from a safe distance most of the time. It should play very well, but might be a bit samey in terms of combat because of this.
