It was nice. The animation was very good in some parts, but in the fight it didn't look like they were punching too hard.
The camera bumps didn't annoy me at all, and neither did the light flickers, and instead, I thought there was some nice cinematography in a few scenes. There's one thing that I would fix: sometimes you pause the action for too long, for example: the guy that enters the room and looks at the machine gun, he takes too much time to decide and take his gun (and plus after that I could see him do nothing with it in the scenes that came after that). Set design was functional to the movie, and the story wasn't defined, but it wasn't meant to be.
Although I don't really care about camera bumps (unless it's a rollercoaster, of course), I would suggest you to use a software like Monkey Jam or Helium Frog (which are free) that lets you capture the frame from the computer, without touching the camera. For light flickers, you should change all the settings of your camera to manual, and that should help too, but I didn't see many, so I guess you could just leave it as it is.
Anyway, 3/5, because it had some impressive shots, overall good animation, but it lacks of a story and it's the same kind of action that we're used to.
