I really enjoyed this map. Currently in the process of finishing my first play through. Have everything done and I'm just grinding the points away for the ending now.
My only real complaint is that there isn't more to it. I would love it if you considered expanding it and just adding more to explore and to do.
As it stands, it has a nice feel of a map that's not way too drawn out and the nice sized training area in the beginning makes it very accommodating to a solo player like myself.
The models are nice and crisp and really lends the BG feel while looking around.
A couple minor things I noticed, though. The extra buttons to open doors had no sound. They simply took away the points which left me wondering what I had opened. Also, you may want to consider some kind of indicator that all of the spy devices have been found. It took me longer than I'd like to admit to find them all (You did a very nice job picking some tricky locations to hide them.) and I wasn't really sure to look for the ending until I just decided to run back and start the next round.
Overall, it was a pleasant experience. Keep up the good work.
