The mouse stays locked even when I alt-tab away which is very annoying.
I don't see the point of having ammo boxes cluttering the quick bar, but that's just a minor issue.
It's hard to tell what's going on and it's easy to lose sight of the enemies but audio and some indicators would fix that.
I see a lot of potential in this, I love systems-heavy games and I like how the enemies are smart, I want to see more enviromental hazards like panels with life support systems that can be turned on and off, light sources that can be shot down and stuff like that.
