Feels and looks like an unfinished game.
Main reasons I don't like this:
-annoying music. (should be more thrilling or ambient-like)
-plain graphics, details are near zero.
-stoned movements
-dificulty-level normal is hard as hell.
-level design, layout - is random as hell.
AI is rather funny, those soldiers are so coldhearted towards each other.
I've seen worse anyways.
This could turn out a little bit better if you would make some major updates.
Ragdoll feature is a big bonus.
