An interesting feature of the map is the stained glass windows. The effect of the shifting sky seen through the glass works well when looking at the windows from within the interior. It doesn't work so well when viewed from the outside, it makes the wall look like a facade undermining your mental sense of the architecture. Also the motifs chosen for the windows seemed out of place in a gothic fortress style map. The architecture is simple and the overall layout is quite flat and spread out with some unecessarily long connections.
The map seems best suited for 5-6 players. (A few missing textures from the ThreeWave CTF pak)
