Very very good actually
Very nice job! Keep doing this, cos' you are so good!
I played it through and it was fun. I found it frustrating couple of times, but it was too addicting to give up.
I liked that combat wasn't based on aim.
I rarely see as good physics as these. And blood was a good thing too (you could really see your damage!).
PS. When you change weapons their reload resets and you can just change between two weapons and shoot rocket launcher and plazma gun like a machine gun.
