Really have to echo what you like about your game, I'm a sucker for garbled character 'voices' for lack of a better way to describe it. I found the slow, deliberate movement to be a solid touch for the type of tactical shooter you were going for, the controls feel weighty in all the right ways.
I really like the concept of the squad mechanics, although my fellows found themselves caught on terrain fairly often. Aside from that I think a feature that could really bring the experience to the next level would be exploring some more in-depth enemy AI behaviors. Taking cover from fire, patrolling, that sort of thing.
All in all an enjoyable little experience!
