Pros:

-Unique style
-Small mazes which is not too confusing
-Messages from other "subjects"
-Scripted spawn of tanks & witches
-Difficulty scales up
-Extremely hard in expert

Cons:

-My eyes hurt
-Witches in narrow mazes are hardly solvable in realism expert
-Difficulty gap is too wide between lvl 2 & 3
-Extremely hard in expert

Conclusion:

On realism expert it's rather a death run map. Level 1 & 2 is quite easy, but it becomes a nightmare since lvl 3. Infinite hordes + multiple tanks + witches/tanks in narrow space = nearly unbeatable. It should be fun killing tanks on normal or advanced, but when tanks can down you in a single hit, this map is a torture.
